As I understand from the documentation, when using ODBC it makes use of connection pooling provided by FreeSWITCH. So I understand there must be a pool where the connections are stored. I am trying to figure out why I keep on getting occasional messages like switch_odbc.c:283 The sql server is not responding for DSN andres [STATE: 08S01 CODE 2006 ERROR: [MySQL][ODBC 5.1 Driver][mysqld-5.6.33-79.0-log]MySQL server has gone away. MySQL is free at this moment and do not have any connections limitation or excessive connection limitations.
