I'm using several RTSP clients threads in my app. Occasionaly in test environment, when RTSP servers are frequently restarted, i'm catching SIGSEGV here :
~"#0 RTCPInstance::numMembers (this=0x7fffaca5e6e0) at RTCP.cpp:234\n" >~"#1 0x00007ffff6246823 in RTCPInstance::onExpire1 (this=0x7fffaca5e6e0) at RTCP.cpp:926\n" >~"#2 0x00007ffff6246873 in RTCPInstance::onExpire (instance=<optimized out>) at RTCP.cpp:694\n" >~"#3 0x00007ffff624417b in AlarmHandler::handleTimeout (this=0x7fffac9437e0) at BasicTaskScheduler0.cpp:34\n" >~"#4 0x00007ffff62445e2 in DelayQueue::handleAlarm (this=0x7fffac001d28) at DelayQueue.cpp:187\n" >~"#5 0x00007ffff6242f8a in CPollTaskScheduler::SingleStep (this=0x7fffac001d20, maxDelayTime=<optimized out>) at cpolltaskscheduler.cpp:204\n" >~"#6 0x00007ffff6243b95 in BasicTaskScheduler0::doEventLoop (this=0x7fffac001d20, watchVariable=0xc73200 \"\") at BasicTaskScheduler0.cpp:80\n" >~"#7 0x00007ffff6242376 in CRTSPv2ClientThread::run (this=0xc73100) at crtspv2clientthread.cpp:223\n" I made some debugging and believe "this" is invalid at RTCPInstance::numMembers. It seems RTCPInstance was destroyed due to closing subsessions, but unshedule() of onExpire() was not performed. What are the conditions that may lead to that ? ps. I use several - up to 4 - RTSP clients per single TaskScheduler + dedicated UsageEnvironment. -- Сергей Куприенко Отдел разработки ПО, "Эф-Эф" Sergey Kuprienko Head of software development dpt. http://www.f-f.kiev.ua +38 097 985 15 69
