Mysql timeout

Hi,

We have to restart every day DB and Pentaho Server in order to work without issues. Issues are related to Scheduler (DB Quartz).

The error is:

Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure


The last packet successfully received from the server was 30,572,478 milliseconds ago. The last packet sent successfully to the server was 1 milliseconds ago.

Platform:
- Linux
- Pentaho8 (Server1)
- MariaDB 10.1.32 (Server2)

Thanks in advance.
