PLESK Frozen when search for domains

[selu]

Hi.

I was removing a domain in plesk when it totally frozen the server. I had to restart it and when back, i get into plesk.
Till here no problem... everything was working except the simple search for domain. In the textfield, was the name of the domain i tried to remove. I can still enter in domain properties, but when i search for domains, it frozen again and again, much times as i have to restart the web browser and login into plesk.

Any clue in what could be happening in such weard thing?!
