             Summary: Locking inversion when attempting to set caller ID while holding iaxsl lock causes deadlock
                 Key: ASTERISK-21192
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21192
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_iax2
            Reporter: Pavel Troller
            Assignee: Matt Jordan


Systems running IAX2 trunks (either with trunk=yes or without it) freeze occasionally with typical symptoms of unreleased locks. The lock appears mostly during the call setup, it hasn't been observed during speech phase or call release. I never found it in 1.6 or less, it appears since 1.8. The newest system on which the problem was observed is indicated below. The only known way to restore functionality is to kill and restart Asterisk. A special debugging Asterisk build has been deployed to one of the sites and core show locks command applied during the deadlock. Its output is attached.
