Asterisk MYSQL ODBC errors

Hello Sirs,

I have random res_odbc errors and have searched on Internet for weeks however there are many toppics about this I did not find an answare.

I have one Centos 7.0 server which is running Asterisk 13.7.0:

I have updated the ODBC to latest version: mysql-connector-odbc-5.3.7-1.el7.x86_64

Another server is running Mysql:
mysql-community-libs-5.6.29-2.el7.x86_64
mysql-community-release-el7-5.noarch
mysql-community-common-5.6.29-2.el7.x86_64
mysql-community-client-5.6.29-2.el7.x86_64
mysql-community-server-5.6.29-2.el7.x86_64

A prefect match in drivers is not available since I already update it.

The error is Random, sometimes days not and somtimes each hour multiple times.

Sometime my Asterisk did chrash but since a >> pooling => yes << it does not crash anymore but still these errors.

It cause realtime issues all over the platform , Extensions, CDRS etc.
