process.send() stops to work under heavy load #3413

When under heavy load (5000-7000req/s) messages that are sent by workers don't reach the master instance anymore.

Tested on Windows 7 x64:
type: Windows_NT
platform: win32
arch: ia32
Node: v0.6.19

As stated here there is a hard limit that seems to cause the problem because especially on windows the message queue isnt flushed as fast as on linux based systems.



Yes, I could reproduce the issue. A fix has been landed in cfa2869 which avoids dropping messages. However there still is no good story for throttling send() calls at the moment.


seems we're past this point.
