Hi!
From: Jan Janak [mailto:J.Janak@sh.cvut.cz] could you, please, generate a core dump ? Use ulimit -c 1000000 to enable core generation and reproduce the crash.
Sorry, but I'm not familiar with core dump, ulimit .... Could you please give me more detailed instructions? Where can I find the core dump?
Then compress the compiled sources along with the core dump and send it to me.
I don't use sources compiled sources, I use the rpms.
regards, klaus
thanks, Jan.

Hello!
During playing around with route headers I discovered that
ser crashes
reproduceable when I send the following request to it with
sipsak, I
think the invite is a valid request with strict routing.
