 Description   

I wish we were using negative memory. I'd spin up tons of processes to get lots of free memory

db.serverStatus().extra_info

{ "note" : "fields vary by platform", "heap_usage_bytes" : -1375415720, "page_faults" : 252 }

chengas123, apologies for the delay in answering this ticket. After some internal discussion, and if I understand things correctly, there are some underlying issues that make this difficult to fix; however, if one calls:

db.serverStatus({tcmalloc:true})

the results are what one would expect. We've opened SERVER-19941 to have this flag turned on by default, so I'm going to close this ticket as a duplicate of SERVER-19941 – but please let me know if I missed anything.

Regards,
Ramón.
