    Description

      upgrade to version 2.2.2. We have 2 node, 1 is master, the other is slave. Sometimes 1 node is crash, here is the crash log. After the crash, the other node is with high load in os level, thread number of mongo increased to around 2000, so linux is overload in system%.

      Os is centos 6.3, with kernel 2.6.32-279.

      Amazon Ec2 16G memory, 4 core.

      Here is the log when crash:
