update_db_cache errors after update to cPanel 70

Hi,

After the recent update from cPanel 68 to 70, we receive the following error on one of our cPanel servers multiple times a day:

Cron <root@SERVERNAME> /usr/bin/test -x /usr/local/cpanel/scripts/update_db_cache && /usr/local/cpanel/scripts/update_db_cache :

Code:

Cpanel::Exception::Database::Error/(XID qv4dmw) The system received an error from the “MySQL” database “mysql”: 1143 (SELECT command denied to user ''@'localhost' for column 'sid' in table 'webform_submitted_data')

        Script::Update::DB::Cache::script("Script::Update::DB::Cache") called at bin/update_db_cache.pl line 36 

Any advise would be appreciated.
Thanks.

 

@cPanelMichael : There is no MySQL user mentioned in the error message as far as I can tell.
