[Serusers] Frustrating error - please help

Thu May 24 20:00:43 CEST 2007

Samuel,
That was very helpful. The last line of the output made me wonder what was happening with the "ESTABLISHED" link. It was CounterPath Eyebeam UA that needed to be restarted. Somehow it was hung and was the source of the problem, not SER.

Thanks for the help,
M

Maybe you've got another software bind to the address SER is trying to bind to(softphone,asterisk,...). Can you check whether the port 5060 is in use?
what's the output of the next comand?
#lsof -i:5060

samuel.

Also a good idea. Still no effect. This installation was working great for a while. Is it possible that some other software I've installed is causing the problem?

This is 2.0.0 rc2 from CVS.

Maybe just try setting fork=yes ?...
