Paul Gorman updated ASTERISK-26261:
-----------------------------------
Description:
Asterisk crashed several time per day. This did not appear to correspond to any particular event in the logs or console debug output.
I got a backtrace of one of the crashes. Based that, I recompiled Asterisk without any odbc options. So far, it hasn't crashed again.

> Key: ASTERISK-26261
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-26261
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Resources/res_odbc
> Affects Versions: 13.8.2
> Environment: Debian 8 (Jessie)
> Reporter: Paul Gorman
>
> Asterisk crashed several time per day. This did not appear to correspond to any particular event in the logs or console debug output.
> I got a backtrace of one of the crashes. Based that, I recompiled Asterisk without any odbc options. So far, it hasn't crashed again.
