Issue Update error

[ScriptBasic]

I recieved the following error when doing my last Plesk Onyx update.

Internal error ;-P
ERROR: Zend_Db_Adapter_Exception: SQLSTATE[HY000] [2002] No such file or directory (Abstract.php:144)<br />

Did Plesk continue to work afterwards and was the update completed?
