I am running mongodb 3.2.7 on ubuntu 14.04 64 bit server. The mongodb server keeps crashing every 2-3 hours. On restart it says this:

stop: Unknown instance:
mongod start/running, process 25687

When I open the mongo shell after this, I see thew following error and the shell is closed automatically.

src/third_party/gperftools-2.2/src/page_heap_allocator.h:74] FATAL ERROR: Out of memory trying to allocate internal tcmalloc data (bytes, object-size) 131072 48

This error was not there 2 days ago. So how can I correct this error?
