After doing "drush cr" getting this error General error: 2006 MySQL server has gone away: CREATE TABLE {cache_default} ( `cid` VARCHAR(255)

My drupal version is 8.5. Not sure why it's trying to create tables.

Hi @lomasr as per reported error message, what i can see here is related to server Time out issue / Delivery of large packet error.

Suggestion:
increase execution time out
increase memory to handle heavy load.

NOTE: make sure to restart the SERVER, once you have made above changes.

This is a common configuration misstep, it's usually max_allowed_packet: https://www.drupal.org/node/259580. Reopen this if that article does not help.
