---------------------------------------

             Summary: Asterisk hang at startup when using odbc
                 Key: ASTERISK-29119
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29119
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: 17.5.1
         Environment: Linux 4.19.0-4-amd64 #1 SMP Debian 4.19.28-2 (2019-03-15) x86_64 GNU/Linux

            Reporter: Dennis Haney


We recently upgraded our servers and we are now getting hangs in startup of asterisk.

Stack trace shows that it is stuck in ODBC. It does not happen every time, but about 70% of the time. kill -9 and restarting over and over until success solves the problem
