I am using aria engine.
Occasionally, when restarting mariadb in the process of using the application, the operation fails with the following error even though no special work has been done.
"mysqld: Got error 'Missing valid id at start of file. File is not a valid aria control file' when trying to use aria control file"

I solved the situation by deleting the aria_log.000000x and aria_log.control files in that situation.

However, from the point of view of a novice user, it is unclear what exactly the aria_log.control file and the aria_log.000000x file do, making them worry about whether they can be deleted.

Is there any factor in deleting the above two files that puts me in danger of not being able to use the data in the DB I have?

Or is it a file that doesn't cause any major problems if I delete it?
