Hi Klaus,

the error shows that shm. mem is full..... :). Even if the TCP 
connection was successfully accepted, it closed by openser since it's 
not able to create some internal structures used to manage the connection.

The shm mem starvation may happen from 2 reasons:
    1) small shm mem pool and high peeks of usage -> try to increase it
    2) mem leak :) -> once you get the error, stop the test without 
restarting the proxy; after 10 min (when the mem used for other 
connections should be freed), restart the test and see if the error pops 
up immediately or not.

regards,
bogdan
