 Description   

Environment:

2 shards with 3 members each (2+1 hidden).
3 configservers.
3 mongos.

Mongod on one of the shard members has been crashing sporadically with nothing in the mongod logs.

Running dmesg on the host shows:

mongod[10039]: segfault at 7f5fc6fe3000 ip 0000003467288bfb sp 00007f5fc6fe00f8 error 6 in libc-2.12.so[3467200000+189000]

The system is idle and only has MMS connecting to it at this moment.

Thanks,

Sadek

We are also running the mongod instances with the following options:
--directoryperdb
--nssize 32
--journalCommitInterval 50
--syncdelay 5

And the databases live on NFS.
