We have several servers with mongodb running. Each server has
several mongodb instances. Mongodb dataset is larger then availiable
memory (mongodb uses memory-mapped files for all disk I/O).
2.6.32 and 2.6.38 kernels periodically crash and crash happens only
with mongodb servers.
2.6.38's trace is in attachment.
For 2.6.32 I only have "kernel BUG at
/build/buildd/linux-2.6.32/mm/mempolicy.c:1489!"
then you should complain to the ubuntu people or whoever provides your
kernels.
