Hello.

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!"

Heed help! :)
