Awesomeb Posted June 29, 2012 Share Posted June 29, 2012 Here's a new one for me, In the morning 7am-12pm the server TPS will sit at ZERO. In the afternoon / night it's usually 17-18. I'm saying the time frame because I believe it's a player or group of players being retards. Currently disabled: Chunk loaders Anchors Rings Tethers Chickenbones addons ( I need it updated to latest forge ) Solar arrays ( needed updated to forge) ComputerCraft Misc EE items I'm on the iPad so I don't remember what else is banned ATM. The server usually is 40/40 players online throughout the day, but at 7am its only about 20. Notes: CB++ didnt fix this Server restarts every4 hours. Any ideas??? Is this some crazy red stone/ timer machine made to purpouslly keep the server at ZERO TPS. Even after a restart it shoots to zero. I7 2600k 16 GB 550 read /500 write SSD Server2008 MySQL on the machine (about 10k players logged in that) Link to comment Share on other sites More sharing options...
Gristle Posted June 29, 2012 Share Posted June 29, 2012 So you have 20 players on a server that is frozen for 5 hours? Link to comment Share on other sites More sharing options...
Nentify Posted June 29, 2012 Share Posted June 29, 2012 Try using a program like VisualVM, it will tell you what part of your server is causing the issues. I can assist you if needed. Link to comment Share on other sites More sharing options...
Awesomeb Posted June 29, 2012 Author Share Posted June 29, 2012 Well, various players over a 5 hour span. thanks Nentify, I used visualVM and did the heap dump ... I don't understand all the classes. Could visualVM point down the exact .class and tell me which mod it is? When I'm back at work I an post the results from the VM. Link to comment Share on other sites More sharing options...
Jay? Posted June 29, 2012 Share Posted June 29, 2012 do you have any plugins? there's a bug with this version of craftbukkit that causes servers with no plugins to eat performance. Other possiblities are cable loops and machines spitting item entities everywhere. Link to comment Share on other sites More sharing options...
Torezu Posted June 29, 2012 Share Posted June 29, 2012 A cable loop would only show up when the machines attached to it are trying to draw power, and item entities on the ground will clean themselves after 5 minutes of server time, so...this is definitely a possibility. Look at who logs on close to the time the major tick rate drop happens. Link to comment Share on other sites More sharing options...
Nentify Posted June 29, 2012 Share Posted June 29, 2012 If you go to the sampler, start the CPU check for a minute or 2, then stop it and press "snapshot". Make sure you've got "Methods" selected in the dropdown menu next to "View:" and open the "Server Thread". Then just open the methods with the highest "Time [%]" and you should find your culprit. I previously had an issue where RedPower pneumatic(?) tubes were using a lot of CPU, and found that it only happened when a specific user came on and found a lot of cobblestone looping round his tubes. I'd recommend taking frequent checks on your users, and as mentioned above seeing if it happens when certain users come online, as they are probably what's causing the issue.

Awesomeb Posted June 29, 2012 Author Share Posted June 29, 2012 OMG. Nentify. You have saved my life. It's not lagging right now.. but that is so awesome! I was using VisualVM wrong. I cannot thank you enough! Link to comment Share on other sites More sharing options...

Awesomeb Posted June 30, 2012 Author Share Posted June 30, 2012 So, Generic Buildcraft Pipe Logged in as a Entity and connected to the machines moving tons and tons of pipes How could I fix this? Buildcraft is huge for tekkit ... I can see removing it.. but that's like 1/3 of tekkit Link to comment Share on other sites More sharing options...
Aegis Fate Posted June 30, 2012 Share Posted June 30, 2012 Buildcraft is replaceable by Redpower, just requires more thought into how machines operate instead of 'Hurr Durr wooden pipes and cobblestone pipes.' Plus Redpower Quarries are total beast compared to a Buildcraft Quarry (Faster and more industrial looking, not to mention it requires experimentation to properly build) Link to comment Share on other sites More sharing options...
Awesomeb Posted June 30, 2012 Author Share Posted June 30, 2012 I just made a test server, doesn't look like I can simply remove [buildcraft] from the server... throwing errors. Plus the Web-Auction looks like its going to throw a bunch of errors with items that are no longer in the game. Looks like a map reset is in order. ---- Update: I can remove all pipes from the server including inventories + ban pipes and placing existing pipes from bags (can't touch the damn bags). This sounds like the best result. a 'lifeless' buildcraft R.I.P. Link to comment Share on other sites More sharing options...
Nentify Posted June 30, 2012 Share Posted June 30, 2012 From what I can see, items are spewing everywhere. Try getting a plugin like NoLagg which groups items within a certain radius to reduce the amount of item entities on the floor. Link to comment Share on other sites More sharing options...
Awesomeb Posted June 30, 2012 Author Share Posted June 30, 2012 Yeah I have nolagg to clear every 20 minutes, + I was doing /remove items -1 (worldedit command) but no luck. Stuff stuck in the pipes didn't get removed. I decided... I can remove ALL pipes across the map, then ban crafting, placing or even having a pipe. I looked into redpower.. that is so much better.

dinxton2 Posted June 30, 2012 Share Posted June 30, 2012 Buildcraft is getting kinda old and obsolete compared to the new and better mods like Redpower.So that means the only reason to have Buildcraft is if you want Forestry, and we all know what happened there...

Awesomeb Posted July 2, 2012 Author Share Posted July 2, 2012 So I've removed buildcraft.. The lag is still very high. I see with /gc I have 8k entities (the clearlag plugin doesn't remove this aswell as /remove items -1). I believe these entities are still screwing us up. (image to large to post) - Here is my latest VisualVM. It's complaining about entities. -- but which? http://www.hellocreeper.com/images/VisualVM.png Link to comment Share on other sites More sharing options...

Hellocreeper Posted July 2, 2012 Share Posted July 2, 2012 I have clearlagg installed, also I try the world edit /remove items -1. They only remove 72 entities. Also, /killall does nothnig. I believe this to be a item from tekkit logging in as a entitie. Link to comment Share on other sites More sharing options...
Hellocreeper Posted July 2, 2012 Share Posted July 2, 2012 Vid7 said its the MK3s logged into the game. Not sure where else to go from here. Link to comment Share on other sites More sharing options...
Awesomeb Posted July 3, 2012 Author Share Posted July 3, 2012 Same issue. I believe a player or players know a way to lag the server out. 0 TPS 7AM until 12PM and then everything was fine. Strange strange. Link to comment Share on other sites More sharing options...
