errors CPU Usage is rising to the sky.

[isteyin]

Greetings to all,
prestashop 1.7.6.5 and i get the following errors CPU Usage is rising to the sky.
do these errors really happen when the server is inadequate?

I usually get this error when clearing the cache.

Uncaught Exception: An exception occurred while executing 'SELECT * FROM is_memcached_servers': SQLSTATE[HY000]: General error: 2006 MySQL server has gone away

Uncaught Exception: An exception occurred while executing 'SELECT * FROM is_memcached_servers': SQLSTATE[HY000]: General error: 2006 MySQL server has gone away
