My server is generally pretty stable. No lag, no random crashes, does not seem to struggle with memory on a regular basis. However, the last 3 nights I've been having a problem with the server crashing and not restarting on its own (which it typically does). I do not have the foggiest idea why. I did not touch anything 3 days ago to instigate this. The crashes seem to happen very late at night to very early in the morning. The server has 3GB RAM and is hosted by Fragnet. The first night, there was only one person on at the time of the crash. On the second night, there were 4, and last night, there were 3. The person online the first night was not on the 2nd or 3rd, so I don't think one particular individual is triggering the crash.

It's very bizarre though, it also seems like the server tries to start itself back up but gets stuck..

This is the server log from this morning at the time of the crash: Pastebin

And this is the full crash report: Pastebin

For the last couple of days I have also been getting the annoying IC2 API error spam ('[WARNING] [IC2] API ERROR: ic2.core.block.machine.tileentity.TileEntityRecycler@4911252f didn't implement demandsEnergy() properly, no energy from injectEnergy accepted although demandsEnergy() returned true.' spammed repeatedly in the console) so I updated IC2 later this afternoon when I brought the server back up. I had thought they might have been related but now I don't know.

Any ideas at least to the cause of this would be helpful. I keep seeing this associated with minecarts and Mystcraft portals but I've asked around on my server and nobody's trying to stick anything through a portal.

Any ideas would be appreciated.

i believe the enet issue can only be fixed by destroying and replacing the blocks, happens to my server alot but doesnt crash anything. I just break the block and replace it and the error just goes away. However one time it did that and took down all eu my server. I think breaking the blocks and replacing is the only fix atm

There is a fix that seems to work for some servers:

@OP, can you upload abit more of the server log, i have the feeling the problem starts earlier then the part what you posted

I don't have the logs from that particular crash anymore but after I posted this thread, the server crashed three times, twice within 20 minutes of each other. I have the log from both of those. Nothing extraordinary..

See Pastebin

The last 12-13 hours have been without a crash, so there's something.

i see 2 things, slytool is moving like hes drunk :p (moving wrongly quiet abit).
before the second crash there is a world ticking error (wich is prob the cause of the first crash aswell).
Either something is overwhelming the server (entities) or there is to much going on i guess

I don't know but the server has been stable (knock on wood!) since the last crash in that pastebin.
