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

I have uploaded the res_odbc and odbc.ini files.  These asterisk servers are not busy at all.  I have an OpenSIPS proxy server that sits in front of my Asterisk servers and it never loses its connection but maybe that is because OpenSIPS is never really idle when it comes to reading or writing to the database maybe?  I also have an OpenXCAP server that doesn't lose connectivity.  When I do a "show processlist;" within mysql I see that all my connections are good and persistent except for the mysql ones.  If I use the res_config_mysql module I don't lose my connection but I do run into a different issue for which I currently have a different trouble ticket open.  https://issues.asterisk.org/jira/browse/ASTERISK-21387

So if I use res_config_mysql my connectivity to the database is fine until I run into my deadlock issue.  I set my logging to debug and I only got this

> For some reason my ODBC connection to my MySQL server keeps losing its connection.  Because of this calls might be delayed until Asterisk re-establishes the connection.
