CouchDB crashed due to 'Cannot allocate 467078560 bytes of memory (of type "heap").'

Looks like couchdb crashed when running pretty moderate workload on Windows.

In diags I can see:

Crash dump was written to: erl_crash.dump
eheap_alloc: Cannot allocate 467078560 bytes of memory (of type "heap").

CouchbDB log:
