I use realtime on my asterisk installation. I have always used mysql for my realtime connection but as mysql seems to be on the "soon to be deprecated" list of asterisk features I am trying to move to ODBC (still using MariaDB/Mysql on backend). I find ODBC support in Asterisk very unstable. Just today my asterisk server (a test server and a production server) has crashed often or simply hangs because it says ODBC is disconnected. I can use the isql tool to query my database without any interruptions.

Is anyone using res_odbc for realtime in Asterisk 13? Both my test server and production server are CentOS 7.2 and I followed the procedure set by the Asterisk Wiki: https://wiki.asterisk.org/wiki/display/AST/Setting+up+PJSIP+Realtime

    I keep getting errors like this one:

asterisk: /builddir/build/BUILD/mysql-connector-odbc-5.2.5-src/driver/desc.c:110: desc_free_paramdata: Assertion `aprec' failed. [Feb 9 16:28:48] WARNING[3781]: res_odbc.c:1405 _ast_odbc_request_obj2: SetConnectAttr (Txn isolation) returned an error: HY000: [MySQL][ODBC 5.2(w) Driver]Lost connection to MySQL server during query [Feb 9 16:28:48] WARNING[3781]: res_config_odbc.c:117 custom_prepare: SQL Prepare failed![SELECT * FROM ps_domain_aliases WHERE id = ?] [Feb 9 16:28:48] WARNING[3781]: res_odbc.c:765 ast_odbc_sanity_check: Connection is down attempting to reconnect...

    Any pointers on working with ODBC and Asterisk?
