I think you end up destroying the same irq twice. Please doublecheck your code.. > 2) From the api documentation it is clear that the destroyed irq should be > in disposable state up to the timer expires. > Please tell me when exactly this timer expires. (i.e., the default > timer value ) The non-INVITE irqs are destroyed once the timer J expires, the timer J duration is T1x64 (normally, 32 seconds). However, the irq can be destroyed earlier if 1) if the NTA is not in UA mode or 2) the response was sent via TCP or TLS > 3) Is there any way that i can put mutex locks in my application to avoid > this synchronization problem. > I am suspecting this behavior as bug in stack. You should protect whole nta_agent_t with a mutex, I'm afraid. -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------------ What You Don't Know About Data Connectivity CAN Hurt You This paper provides an overview of data connectivity, details its effect on application quality, and explores various alternative solutions. http://p.sf.net/sfu/progress-d2d _______________________________________________ Sofia-sip-devel mailing list Sofia-sip-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sofia-sip-devel
