For me there's nothing wrong with your configuration, apart from maybe 
the 1000 threads. If you are using 32Bit Win, then it's likely, that you 
will only be able to produce something between 400 and 500 threads.

What about reproducability of the error?

The one parameter I'm having least experience with, is socket_timeout. 
Do you still get the error, if you do not use socket_timeout and lower 
your thread number to 380?

Regards,

Rainer
