Cerber_log mysql table

Not sure where to post, but my hosting account was suspended due to the mysql database taking up too much of the server resources. The cerber_log table appeared to be at fault, beginning with this error:
| 115261504 | bassoons_webUser | localhost | bassoons_execCoaching | Query | 3575 | Waiting for table metadata lock | ALTER TABLE cerber_log CHANGE stamp stamp DECIMAL(14,4) NOT NULL | 0.000 |

Is this common for WP Cerber plug-in to alter the log table? This looks very suspicious to me, like hacking or a MySQL injection.

The SQL request (‘ALTER TABLE cerber_log CHANGE stamp stamp DECIMAL(14,4) NOT NULL’) is completely valid. No bad actors are involved here.

I do not see any reason why it would create difficulties for your hosting provider. Do they really count every single SQL request to a website database?
