Recently (over the last 5 days or so), my FTB Unleashed server has been crashing (full crash dump can be found here).
The server is being hosted by Nitrous Networks, and is running on a Linux OS with 2 GB of RAM available. It's running FTB Unleashed version 1.1.7 against Minecraft 1.5.2. I haven't added any mods or modpacks outside of what's already included in Unleashed, nor have I manually updated any of the modpack's mods to newer versions.
Unfortunately I haven't been able to identify any patterns behind the crashes, they're happening at seemingly random intervals, sometimes very shortly (within minutes even) after the server is rebooted following a crash, sometimes it will last several hours/half a day between crashes.
I suspect that something has changed or that someone has done something specific roughly 5 days ago - prior to then the server ran without issue for almost a month.
I've spoken to the vast majority of users to find out if any of them had done something unusual or new around that time, but nobody is owning up to anything. I've tried removing all of the Mystcraft dimensions from the server and then rebooting, although that was something of a stab in the dark and hasn't resolved anything.
Has anyone seen something similar to this and could give me a nudge in the right direction?
Update:
Setting load-chunk-on-request to false in bukkit.yml appears to have stopped the crashing, but we now have a slow memory leak necessitating 8 hourly server restarts.
