Infinite loop in jbuf causing deadlock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have tried to list possible scenarios that may lead to the problem,
however I couldn't really find one, so far my only suspect is there
was a random jump of RTP timestamp. Is there a bit more pointer that
may help us to reproduce the scenario? e.g: RTP packet logs (from
sniffing tool), call time, sip provider (if possible).

Regards,
nanang
