    Description

      A mongo DB server was recently upgraded from 2.6.1 to 3.0.6 on a Windows Server 64 bit. What we see is that every 10 to 15 mins the mongodb database becomes unresponsive.

      The mongo clients are mainly PHP mongodb driver and libMongoC driver. We disabled the libMongoC driver and left the PHP mongodb driver and it still caused the same issue.

      We see that the following in the log, the full log is also attached. Basically a lot of open connections coming in and not getting serviced or closed.

      Switching back from 3.0.6 to 2.6.1 makes it stable again.
      Can you please look and tell us if there is anything we can do to address this issue.
