          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_pjsip
    Affects Versions: 13.28.0
            Reporter: Salah Ahmed

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
