Please. Look at the forum you posted this in. Notice the global announcement with your exact error in the title? Read that post and follow the instructions in it. Know your php and zend optimizer versions, then ask yourself if you want to try a hack or a patch. Either way, the development team can't help without good information.

Oh and please use the subject field when posting. No subject is even worse than the dreaded "problem" subject. A description of the reason you're posting is really cool. And not so hard to do.

I'm locking this topic.
