Hi! I'am trying to use pjsip source in one iOS project. When I am testing it on my devices all works fine. But when I sended it to review they get some troubles. Application stalls when I call pjsua_init. And now I can't find reasons of such behavior. Here is part of crashlog: Applicat failed to resume in time Elapsed total CPU time (seconds): 11.230 (user 7.560, system 3.670), 56% CPU Elapsed application CPU time (seconds): 9.140, 46% CPU Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0: 0 libsystem_c.dylib 0x32cca708 _spin_lock$VARIANT$wfe + 44 1 libsystem_c.dylib 0x32c934e8 pthread_mutex_destroy + 16 2 Applicat 0x00028208 pj_mutex_destroy + 24 3 Applicat 0x000282d8 pj_thread_destroy + 20 4 Applicat 0x000ac710 pjsua_destroy + 72 5 Applicat 0x000ad074 pjsua_init + 936 Thanks!
