Dare Awktane commented on ASTERISK-21662:
-----------------------------------------

We do not use sip users table but we do have most of the other tables in a mysql database which we connect through odbc. I checked a number of our log files for the past few days and we do not see this issue. I have seen disconnects in the past but it happens very rarely and it is almost always explainable (mysql server restart,etc). Out of curiosity would you mind posting both your /etc/asterisk/res_odbc.conf and your /etc/odbc.ini file (with any passwords,etc blanked out as necessary)? How busy is the database? How busy is the asterisk server? Does this happen during points of particularly high or low traffic? Any other information you can give us that might help narrow this down would be excellent. Without being able to reproduce it or some information that gives a direction it's almost impossible to help.

> 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.
