Re: [reSIProcate-users] endless Re-Invite ping-pong

[Daniel Goergen <daniel.goergen@xxxxxxxxxxx>]

Hi Byron,
Thanks for your answer!

I tried to reproduce the problem with Debug log turned on but I didn't manage it yet (it's, of cource, a very unlikely race-condition). The Info logs I had was copied from the windows console and I didn"t check to cut the matching timestamps. When the problem occured last time, I had both sides in debug mode with breakpoints at the (few) entry-points to my app, so I'm quite sure this message ping-pong is not caused by the app. I'll keep the Debug log running and hopefully I'll catch the problem soon.

Best regards
Daniel
