Hi all. I'm having some problems about pjsip for symbian .I have read the documentation (http://trac.pjsip.org/repos/wiki/Symbian_AP_Reconnection).Then I code my app by imitating symbian_ua. Register is ok.When I am calling someone, suddenly connection is lost. Some problem happen to my app.Sometime my app is deadlock,it can do nothing again,sometime my app is ok, it can reconnect to WIFI and register again. I debug my app,I found the code lines when the problem happens,but I don't know how to solve it. The code lines when the problem happens: Code File: project-1.7/pjsip/src/pjsip/sip_transaction.c Code Function: static pj_status_t tsx_destroy( pjsip_transaction *tsx ) Clde Lines : lck = (struct tsx_lock_data*) pj_thread_local_get(pjsip_tsx_lock_tls_id); while (lck) { if (lck->tsx == tsx) { lck->is_alive = 0; } lck = lck->prev; } When my app is deadlock,.lck->prev(lck) is 0xFFFFFFFF,the app can't be out of the loop,But when the my app is alright,lck->prev(lck) is 0x00000000. Is this bug? Please help me. -------------- next part -------------- An HTML attachment was scrubbed...
