> Hello,
> Recently we experienced a crash. This crash happened during execute "pjsip show channelstats" by an external module. It seems this is a separate thread running to fetch and print rtp stats. Actually the crash happened on ao2_lock, just before it going to read the rtp stats on a rtp instance. According to gdb backtrace log, it seems the session media was already cleaned up at that moment. 
> Thanks,
> Salah
