maybe I found some more severs for generating load :-)
I also suspect SIPP to generate wrong messages sometimes and it crashes
during high load when using multiple TLS connections.

only one UDP socket: no TCP, no TLS, no loopback-device. strange.

what is a name of a socket? I only see:

graham:/home/darilion# netstat -anp|grep openser

I try to reproduce them.
