My configuration :
Win Seven
Python-2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)]

The context:
Several programs using zmq successfully launched as windows services that
run simultaneously on the PC.

The error:
when too many programs (about 10) using zmq run and I want to launch a new
one, I get:
"Assertion failed: Accès refusé.
when I call zmq.Context().

Already tried without success:
- Increasing Windows TCP socket limits by defining:
MaxUserPort: and TcpTimedWaitDelay as explained here:

The problem is probably related to "ephemeral port" but I dont' know how to
fix it.

Thanks for any help.
