Question MariaDB GSSAPI crashing - does Plesk require the GSSAPI plugin?

[gbotica]

Hi there,

I have a relatively new Plesk Obsidian, CentOS 8 server. I am getting frequent mysql crashes.

The mariadb.log has many of these:

2020-05-09 23:01:50 0 [ERROR] mysqld: Server GSSAPI error (major 851968, minor 2529639093) : gss_acquire_cred failed -Unspecified GSS failure.  Minor code may provide more information. Keytab FILE:/etc/krb5.keytab is nonexistent or empty. 
2020-05-09 23:01:50 0 [ERROR] Plugin 'gssapi' init function returned error.
2020-05-09 23:01:50 0 [Note] Recovering after a crash using tc.log

I don't really know if Plesk needs this GSSAPI or not? Nor can I figure out how to resolve this error.

I realise this isn't regarding Plesk directly, but I need to figure out if Plesk depends on this GSSAP plugin?

Thanks
