We've compiled kamailio with mem debug, but now kamailio is very, very 
slow, so that it's really not possible to make a stress test. We were 
able to place one single call (The INVITE took aboute 1:30 min until it 
reached the destination).
The memory status at shutdown is available at:

Hopefully this will be helpful.

Thanks for your help,
Christian
