[pavkrej]

Hello,

I installed Zend CE 5.6.0 SP1 on product machine 2 months ago.

Software:
Windows Server 2008 R2 + IIS 7.5

Each day I seeing few error:

Report Id: 36327184-d8c8-11e1-bd47-000c2919a4ec

What can I do for fix this error?
(With standard binary files from php.net doesn't happen, but it has less power)

Thanks
