Hi. During the standard mail.box maintenance, 1 database was damaged.
The following was output to the console:

After that, the database became unavailable, and the following entry was constantly in the console:

A commit was launched on the database, but it did not help.:

As a result, the database had to be deleted with a server restart.
Question: What caused this error?
How to fix it is clear. But why is the base damaged?
