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

bq. With latest unixODBC I didn't see crashes after 1 day, good news I'll test for some days more.

Great! Let us know.

 Thanks for the write up. I'll see if we can use this on the wiki in an appropriate spot.

> testing release 13.8.0 I found crashes making heavy use of ODBC with mysql. This issue seems to not happen in 13.7.2 release.
> We make a heavy usage of mysql using ODBC, dialplan functions and CEL. The isse seems to happen with 4 or 5 calls using queues, cel logging to mysql and lots of database calls in the dialplan.
>  I think maybe related to Change-Id: I37a84def5ea4ddf93868ce8105f39de078297fbf (res_odbc: Remove connection management) because it directly affects to odbc connection settings. 
> I will attach some backtraces where you can see clearly the issue is related to odbc and libmysqlclient.so.18
