bq. I'll test for some days more and if everything is OK I'll close the issue.

Thanks. If things work out then before we close the issue we should look at updating the wiki or other documentation to help others out who run into your scenario.

> 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
