Michael L. Young commented on ASTERISK-24450:
---------------------------------------------

Just to clarify my earlier comment... It was based on a quick search done based on what I saw in the backtrace.  Rusty has already pointed out that it would look to be a bug in libodbc.  I was searching to see if there were any known bugs in libodbc and the second result from google showed this issue: ASTERISK-14161.  On that issue, a developer asked the user to try setting idlecheck.  That was all that was on that issue and it was closed.  So, I didn't put too much thought into my simple question except to think that maybe the connection to the db server was being closed and therefore causing the crash.  I tend to start with the quick, small, simple, back to basics type of things when it comes to troubleshooting since in most cases that is the fix before diving deep into other possibilities.  As Rusty pointed out, you cannot really compare 1.4 with 12 since there have been a lot of major changes.

With the detailed information that Rusty has given you, hopefully you can track this down and get it fixed.

> PFA the backtrace. Asterisk 12.4 crashes randomly in production. It looks like crash due to static realtime. We use MS SQL Server database and the agent info and credentials are stored in remote db. We use func_odbc.conf to read password from the db.
