At last, it seems the problem is solved for now. I (as in the server) was running an outdated version of Java. After updating it to the latest version, the issues stopped. Likely of note is that the person who was just crashing the server had a newer version, so if someone has this problem, it might be from Java version, which is a solution I could not find.

Now-crasher is using Java 7 on Win7, the _only_ lead I have is Java 7, gonna investigate online

Having the problem again, with a different user now, no ideas on how to proceed

Right now the best theory I have is that the crasher (from post #3) is using Java 7 on OSX. We are going to at some point see if they get their ban message on Java 6 without crashing the server. If they do, I'll make sure to make mention of it here.

Noticed the update to the launcher, while it might just be a coincidence, this issue hasn't appeared again.

Very interesting incident just happened, server was lagging a lot (I think from a combo of misplaced wrathlamps and water in a quarry requesting tons of chunk updates), and one of the regulars (who also tends to be the most frequent crasher) joined, server crashed. I set a ban on both them and everyone else who was on the server at the time (reason: no join ATM), and apparently they tried connecting (with the ban in place), and the server crashed, despite the ban. I have absolutely no idea how the heck this could have happened. Any thoughts?

Just got another one of the crashes, same trace. Moving the player through the player.dat didn't fix anything, I'm just deleting them from NEI and the player list and going to give them what they had. The spot they spawned in didn't have anything odd about it. It was also in mid-air on the second crash. I currently believe that this crash happens after gravity is applied to the velocity, but before position is adjusted by velocity. I had zeroed the velocity, and there was a slight downward velocity in the player.dat. Their inventory was entirely of Vanilla items, and I don't suspect inventory itself to be the cause of the problem. I backed up the player.dat before deleting it, and can report values from it on request. A previous theory I had on the crash was that it was related to a player intersecting an object, but that doesn't seem to be the cause, as moving the player up into the air didn't fix it this time.

In case anyone is wondering why I keep posting as I find things, it is both so that the most recent information is availible, and so that there are more things that search functions (both forum-based and Google) can pick up on, to hopefully help other people with similar problems fix them, basically to avert XKCD/979

After digging in my logs, OpenAL seems to be the cause, or rather the failure to load it. It also appears that copying OpenAL32.dll to my Windows\System32 doesn't help. I shall do more research into getting OpenAL installed on a system-wide level.

Some players on my server now seem to be crashing the server when they join, and I'm having no luck finding the source of the problem: java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(Unknown Source) at java.util.HashMap$KeyIterator.next(Unknown Source) at ii.a(EntityTracker.java:237) at net.minecraft.server.MinecraftServer.r(MinecraftServer.java:692) at net.minecraft.server.MinecraftServer.q(MinecraftServer.java:599) at bdz.q(IntegratedServer.java:170) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:497) at fy.run(SourceFile:849) Any thoughts/information?

After a bit of searching, I came across https://mojang.atlassian.net/browse/MC-11030 (Resolution: WAI)

It seems to me that, numerous times (I thought this was related to addition of new mods in my install, but I'm not sure not), sound won't start with the game. Syntoms include not hearing that initial "click" sound, nor any other sounds. Sometime, it starts some time into the game, but not always. For those interested, my current "pack" is at http://cdusto.selfip.com/technic/cDM-1.0.zip (I also have it on the Technic platform, mainly to help with multiplayer, but the core is Tekkit Lite, as is what _I_ launch.) I've already seen if F3+S helps anything, it doesn't. Any thoughts?

It looks like it _might_ be a block ID conflict, on 4092. In my configuration, immibis.tubestuff.BlockTubestuff has 4092, while openccsensors.tile.gaugeblock has 3892. openccsensors.common.blocks.BlockGauge doesn't show up in my IDMap dump. Try the following: * Disabling OpenCCSensors (remove the mod from the mods/ tree) * Having NEI preform an IDMap dump * Editing the config/OCS.cfg file, setting the block IDs to free ones. * Restoring OpenCCSensors to the mods/ tree For future reference, this was _not_ a NullPointerException, but an IllegalArgumentException.

IC2 Halloween event, problem is no longer

No one level actually _has_ all the ores. While I can't find them right now, there are charts floating around which indicate the density per level. FWIW, Vanilla (iron/coal/gold/diamond) ores are best at 11. Personally, I dig shallow if I need copper, deeper for tin, and deepest for silver. Uranium and quartz are found everywhere IIRC. Ferrus is a deep ore, as is tungsteng, but the latter is completly useless. I forget how deep lead is, but it isn't the deepest of the ores.

Something about Windows 7, have you tried: * Stopping the Indexing Service (Windows Search might be eating CPU) * Disabling audio enhancements (audiodg.exe might be eating CPU) * Updating system drivers (outdated drivers might not be as efficient as newer ones) * Stopping background tasks I can pretty much guarentee that you _WILL_ get lag in Tekkit Lite, due to the huge number of additional blocks. Something else that helps me is to switch Tekkit to be windowed, bring up my process list, and see what has the biggest CPU usage (excluding the java process hosting Tekkit). I've noticed that, at one point, Explorer itself was eating up CPU, reacting to every file change in the save folder, but an update fixed that.

It should actually work now - there is an IC2 glitch which triggers around Halloween, where it tries to spawn mobs wearing the advanced armors. The null pointer was at ic2.core.IC2.onLivingSpecialSpawn(IC2.java:2270) which helps to validate this theory. If waiting until Nov 2nd doesn't help, try adjusting your system clock further forwards.

It is interesting seeing the single-layer thick bedrock at the bottom of a massive quarry I dug. Also still getting the problem, so bump.

Found an...odd solution to change the username. Apparently trying to "log in" with the desired username (rather than your e-mail address) works. Not as automatic as I hoped for, but w/e Any solution for the offline skin, short of replacing Steve? in the files?

Another day, another bump

(For some reason, the Edit functionality isn't working for me ATM; the text area goes blank and is uneditable) I _do_ have the capability of setting a proxy on the system, providing I'm able to SSH into my server (proxy over SSH FTW). I'm normally able to do this, but I tend to have problems where there is no network connection. However, Minecraft doesn't seem to like the use of proxies. Another 'solution' I came up with is suspending the javaw.exe process, but this is not only unreliable (I've noticed it doesn't always resume correctly), but also doesn't take care of situations where I need to restart Tekkit itself (crashes, reactor monitoring equipment malfunctions, config changes).

At my college, I keep running into the problem of offline mode; the username assumed by myself is different online and offline. This creates problems for me in many areas: * Permissions on Forestry blocks * Frequency list for Wireless Redstone * Tesserect permissions and list (?) * (In theory) Trade-O-Mat and Personal Safe * (Potentially) Skin Is there any known working solution for this? I've already tried one mod to fix it, but it didn't seem to help.

It does, but I need reasons to use RP in a system instead of BC. I'm familiar with the thing that BuildCraft can do, but need good reasons for some things where RP is better.

I have been running Tekkit Lite with Forestry and Railcraft installed, and have dedicated my current base as a project to create a skyscraper which demonstrates cooperation. As part of it, I need ideas for unifying these four very different automation systems. The core of my storage is an AE network, which currently extends from B2F (AE Central Processing) to 2F (Computer lab; gonna set up Redpower and Computercraft computers here to work in cooperation), skipping 1.5F (temporary bedroom level which will be knocked out to make a 2-story lobby). I know that the absolute core of the skyscraper will be the AE network. Out back, in my greenhouse, I have AE serving a small wheat farm (mainly for seed oil for Forestry), but the main thing back there are my bees; I have BuildCraft pipes serving to automatically breed the bees, as well as to sort out the stuff to send to the ME (combs, pollen, and jelly). I ran a small experiment with replacing the setup with the Logistics pipes, but ended up going against it since a QuickSort module on the ME interface I had back there didn't pull the bees from the ME to sink into dedicated chests. I have decided that eventually, I might make seperate buildings from the skyscraper, like a train shed that is completly detached from the skyscraper. I have already decided that I will run Logistics over to those buildings; while I won't be able to request central crafting, it will really save on the quartz cost. I have practically no experience with RedPower tubes, nor much of an idea of what I will end up using them for. Probably small-scale automation which should be seperate from the ME system, like I'm doing with the BuildCraft pipes, but I need to know the big differences between the two systems, aside from RP being destination-oriented while BC is flow-oriented. I also know that I can make the following "interfaces" (of such): * Logi feeds BC through sinks, BC feeds Logi directly * Logi feeds AE through sinks and request, AE feeds Logi through provider * BC feeds AE through interface, AE feeds BC through interface (does export bus work for powered output?) * I don't know how to reasonably connect anything with RP Any input on the project, or information on RP pipes?
