      I seem to get oom crashes on my VPS.

      you will find attached the mongo log file, as well as the diagnostics file data.
      (please note that I am not sure if this is an actual bug)

      Additional notes:
      the crash happened when the application server was idle (no users connected),
      when stress testing the application server (100 concurrent users), mongoDB performed as expected,
      when the same crash happened in the past, I noticed that the performance counters PerfOS (DLL Name: %SystemRoot%\System32\perfos.dll) had been disabled and I had to enable them manually (my application server uses them as well, that's how I noticed).
