Calee initiated <bye> and destination address is a hostname not IP address.

Message:
Yes, it is easy to reproduce.
If no replacement of hostname to IP is done, then it coredumps.

No other core files exist.

Message:
That does not show anything interesting. MAybe there is another core file
from another openser process which acutally crashed?

Can you reproduce the crash?

my fault. please enter 'bt' without #

Hi Klaus!

Didn't include "# bt" output, since it was just a blank line...
