Hi, With the aid of the Borland debugger, I?ve found a deadlock situation between two threads when using the latest pjsip 2.0 code from SVN (checked out April 1st). The issue is similar to the one fixed in ticket 1451. Thread 1 attempting to send a packet: - ice_strans.c: pj_ice_strans_sendto (line 1191) acquires turn socket lock - ioqueue_common_abs.c: pj_ioqueue_send (line 906) attempts to acquire key mutex Thread 2 receives a packet: - ioqueue_common_abs.c: ioqueue_dispatch_read_event (line 418) acquires key mutex - turn_sock.c: on_data_read (line 548) attempts to acquire turn socket lock Regards, Jonathan Martin AKCode LLC -------------- next part -------------- An HTML attachment was scrubbed...
