First thing to check is to make sure you have plenty of hard drive space. This is one reason mysql will crash.
If you have plenty of space, we will look into something else.

What is caused due to a lot of ram memory usage?
Here's a Screenshot of the memory usage ram.

http://dev.mysql.com/doc/refman/5.6/en/mysql.html

mysql --user=root --password=your_password

your_password is the one you find in /etc/sentora/panel/cnf/db.php
