Below is the crash report the server saved to disk. I couldn't find anywhere more specific to post it and @Dinnerbone is always telling people to report bugs.
I realise we can (and how to) increase the RAM the Java process is allocated, but we have problems with the server running out of physical memory (it has 8Gb) and it starts swapping to disk and everything slows to a crawl.
Possibly related: we are almost constantly receiving "Can't keep up! Running 401652ms behind, skipping 8033 ticks." messages in the log. That's an extreme example, but it's almost always 20-30,000 ms, 400-600 ticks. This Debian 7 server has four 2.4GHz cores, 8Gb RAM and is running on an internet connection way better than fibre.
