Hello.
We have two servers with mongo database. Mongo uses memory mapped
files so almost all host memory is busy. About two times a month
kernel panic happens.
I've attached screenshot of kernel panic trace. Can kernel panic be
caused by igb driver? I tried to get full trace with netconsole
module but did not recieve data from the server after crash.
