I have a Ubuntu VM instance on Azure. Without any anomaly in the code or activities carried out server freezes and when I try to run any command it pops up a -bash: fork: Cannot allocate memory
.
I have a python server running along with a mongodb and mysql. I don't see any reason for such disk access. Also there is no significant or CPU or network IO load.

Has anyone experienced such behavior? I haven't seen such behavior on my test environment or for nearly 14days in production until today.
