Title: Crop Matron + Stacked Weed-Ex = Instant server crash Version: 3.0.3/3.0.4 OS: Linux Ubunto 11.10 64Bit Java Version: Java 1.7 64Bit Description of Problem: Server crashs instantly upon loading of a chunk that has either gotten Weed-Ex /give'd to them, or duplicated via a short term rollback. Weed-Ex stacked in a crop matron instantly crash's server upon loading of the chunk. This is more of an informative Bug rather that an issue seeking a fix.

Grats on entering the Deluxe section!

Wrong place bub.....Incoming whale box.

ATI sucks, go buy a Nvidia card. Catalyst drivers for the 4 and 5 series cards cause this issue with MC/Tekkit. I had to completely rip out my 4870 x2's on QuadfireX and replace with GTX 550's on SLI because i didnt want to dip my performance in other games. Boring story short. You are most likely using an ATI card thats in the 4 or 5 series, and nothing you do will fix it, trust me. Go buy an Nvidia.

This thread took a huge turn for the...win. In all seriousness, if you cant handle the burn, gtfo of the fire. Running websites of this size is a huge responsibility. Running websites of this size, while updating technic, and dealing with stupid shit that could be avoided by simply educating yourself on the rules and proper posting procedure of the website/forums while not being paid to do so. BIG FUCKING STRESS. Lighten up or go home. Hopefully you have learned something from this. Take your broken ass record player and come back when it is playing an acceptable tune.

Indeed, its good to see a few more people putting effort into showcasing their servers and attempting to atleast make it something more than a pit of despair.

Give me a link, its 2am here, working on server, and ripping up my tile floor to do oak flooring.

Perhaps i didnt properly convey not only my feelings, but what i was actually trying to say. From day 1 of updating to tekkit2, the servers RAM has slowly depreciated until the server would either crash, or need a restart, this hasnt been a issue that has arose in the past 1-2 days, we had to specifically implement countermeasures just to keep the server up, that included modifying certain config files and applying a Autobackup plugin to auto restart every 2 hours to prevent a crash/rollback. The most recent issue, was that it would crash every few seconds after coming backup, it would usually take 200-700mb a second, and dump it until there was none left, and it would just crash. Now, in no way was i attempting to blame this on code, i should have worded it better. I was merely asking if there was any possibility of the code being revisited in the future, and tweaked to be more large scale server friendly. Thats all. As for the Viri, it is very probable that someone had loaded a malicious program into their computer console, in an effort to subvert the server and take it down, as we didnt think to need to have them limited to certain ranks, something we most certainly CAN do using perms and configs. it also does not help that they are literally able to be crafted from bottom rank items, which in turn makes them extremely easy to acquire and distribute. Kaker, in the instance of RAM usage you speak of, it would continue to take more than was allocated to it, and would sometimes not only freeze the container, but there have been atleast 4 instances where it crashed the server hardware, because it attempted to take more than was actually there. Which is not only ODD, but downright unexplainable by me, as im in NO WAY good with code and programming. Even our host, who is majoring in...whatever (insert computer course, certification, code, language here) could not figure out what was causing this issue, an therefore continued to allocate more and more memory until it reached a point where there was no more to allocate to the memory dumping. I patiently await your wise responses.

So, we, being Terra Novo, have been running Tekkit2 for a solid 8 days now, due to the nature of this error, i will not be able to supply any error reports on the subject. The server as a whole has had to scale its allocated memory back quite a bit because there was a gigantic memory leak that would literally cause the server to go down every 3 hours. So we setup auto-restarting for the server every 2 hours, which usually was just barely enough time to keep it from crashing. Since then, the problem has gotten worse. As of today, the server started experiencing severe issues that would take the server down in a matter of seconds. So we whitelisted the server, thinking it might have been a machinery issue, and it wasnt. We swept through our entire backend testing things out, and finally decided to turn off computercraft to see if maybe that was an issue, IT WAS. Not only did it solve our problem, whichw as the server eating ALL of our memory in a matter of seconds and crashing, but it fixed the memory leak that would steadily over the course of several hours, kill the server. I dont know whos responsible for updating or approving mods for tekkit, but it seems that this mod was not tested, or even designed for large scale usage. Which is a huge shame.... I am including a few graphs to show the memory usage/spikes from our server, against the graph of another server in the same network: here is a server on the same network, aside from the 2 world edit crashs you will see, the CPU usage is very stable And now here is our graph taken the same day, the two sections where it completely runs out of memory were the issues we were experienceing, but notice how our memory usage through out the day is really up and down? Since removing Computercraft, our memory has been very stable and almost perfect, we could most likely support upwards of 200 players now without this issue. If its possible, and if the author/authors had the time to actually do it, maybe look at the coding and fix the issues with it. I know not having it is going to suck for a lot of people, including me, whos entire town is rigged with computer security consoles. Thanks guys, and keep up the good work. ^_^

With the amount of memory leaks Tekkit already has, Dynmap would effectively cut a servers maximum server population in half. If the memory leaks could be fixed, i would most def support the allocation and development of this mod for Technic ^_^

Our perms work just fine, and we use PermsEX, let me take a look at your perms...Ill let you know.

Im having the same issue, and before i drop this into Terra Novo, i was planning on testing it on a temp server, however, this is the WRONG place for this post, you would have done better in the Bugs Forum.

Current setup is 8 different ranks, lowest is visitor, unable to do really anything including build until they register, then websend updates. They can use basic functions like helpchat and whatnot, Citizen has access to home/sethome, we had a HUGE issue with these two commands working properly. Kits are also working and each rank except visitor has their own kit. Quality of life perms are given at next above citizen, and the list goes up. When i have time, ill sit down and write it all out for you so you can update the thread. Basicly everything that youd expect a server to have working, does, and the perms have all been worked out just fine. Ill update this in 10 hours. Be back soon.

Herp. Top config is permsEX config, middle is towny. bottom is Essentials. ENJOY!!

I figured i should share this, considering this community needs more exposure and love. We spent 2 weeks debugging the perms and finally have a flawlessly working perms setup for large scale server support, complete with working ranks and websend garbage. HERP, also need to add the config files and such, but it works great, we will be debuting our Steampunk RP/PvP server named Terra Novo using this package very soon, if you are interested in checking us out, visit us at terranovos.enjin.com.
