I hope I'm posting this to the right place. Apologies if I fuzz up.
I've been running a low-volume (2-3 users max) TechWorld2 server since 18.104.22.168. Upgraded to 22.214.171.124 as soon as it came out.
While people are using the server, it will crash after a seemingly random amount of time, or simply shut itself down.
Here's what the log says just as the users are disconnected and the system stops responding:
At this point, I either have to restart the system because it shut itself down, or kill off the processes manually (kill -9 required, graceful exit requests are ignored) and restart the service.
It also crashes. The following logs are preceded by excessive memory usage and high CPU loads (230%+)
Best guess I have is that some chunk is loading with some item in it that's causing it to run away with a memory leak.
I tried RotaryCraft, but the windmills crash the server on placement. So no-RotaryCraft items are placed.
I have the following items:
Even with just my chunks loaded, after a few hours, it will stop working. With 2 people on, it survives less time, but usually no less than 30 minutes.
- 4 Electric Furnace
- 2 Generators
- 1 Batbox
- 1 Metal Former
- 1 Compressor
- 1 Ore washer
- 2 Macerators
- 4 Barrels
- Several iron chests
- Blast Furnace (HLSA, not vanilla steel)
- Wheat farm
- Ender seeds
- House made of stone bricks & wood stairs
It also likes to crash after building nether gates, but that might be coincidental.
Anyone else reporting a similar issue? Problem with the upgrade from 1.0.1 -> 1.1.1?
Thanks for your assistance in advance and putting together such an awesome mod pack!

Thanks X3773, but it just "crashed" again. You see it save the world, then close the server down. Just started it back up again.We had the same problem before. The fix we had for it was to increase the Perm Max. It's related to java running out of RAM to create the needed classes, this is not related to the max you give the minecraft server.
Add the following to the start up extra arguments of the server. Increasing to 128MB or 256MB should fix your problem.
I am waiting on a couple fixes before release. You can manually update. There's been quite a few unique new bugs this go round that I have to track down and hopefully find fixes for.Has this update been postponed? We are eagerly awaiting to start using RotaryCraft again.

I see quite a few of those. However... I am seeing some oddness in the firewall logs:2014-02-09 17:00:06 [SEVERE] Reached end of stream for *.*.*.*
Looks like ACK RST packets are being dropped. I wonder if that could trigger Java to throw an exception and that's what's crashing it.

What were you doing at the time? This looks like a different mod interfacing incorrectly with TE.
As i run a server and i was not on the server at the time i cant tell you what caused the crash but i can tell you that this is not the first time it crashes with the same error. There is another similar error that caused a crash but i cant tell you either what is the cause of it.What were you doing at the time? This looks like a different mod interfacing incorrectly with TE.
Thats usually only seen when either 1.) the railcraft hidden block is on, which it isn't in the default configs. or 2.) another mod is interfacing incorrectly. Its a cross mod bug, but I am not sure which mod. I'll see if I can figure it out.As i run a server and i was not on the server at the time i cant tell you what caused the crash but i can tell you that this is not the first time it crashes with the same error.
