Odd crash of PLESK admin panel

[tkalfaoglu]

Hi.. Today at first I could not login to the panel (10.4, all micropatches).. The panel would not show up.. Then after a few tries, I got this error:

ERROR: Zend_Db_Statement_Exception

I rebooted the machine (linux centos 64) and the control panel appears fine now..
Was I hacked? Why the crash? What does it mean?

Thanks, -t
