Any advice would be great.


Yeah, looks like you have no swap. :-) Or at least nothing enabled.

Also, here are settings we use for 32-bit VMware servers which although
had plenty of RAM (24GB), were exhibiting OOM errors:

vm.min_free_kbytes = 16384
vm.overcommit_memory = 2
vm.overcommit_ratio = 75
vm.lower_zone_protection = 80
vm.swappiness = 60

Using these settings, our OOM problems have gone away.
