Looks to be running out of lowmem.
# date
# cat /proc/meminfo
# cat /proc/slabinfo
Run a script that dumps the above every 1 to 5 mins. That should
help explain the cause.

These log items appear and the server crashes. Has happened twice now
at three week intervals, each time during a heavy IO operation:

Can't find much on any of these errors…what is 507 ERROR status = -12?
Any help appreciated
