I have Zend Framework(version 1.10.8) and Zend Optimizer(3.33) installed on the server.

Hmm ... ok well it must be something else then ... unortunately this issue was the only thing I could find. If you understand German though there somebody had similar problems but he was using Zend with Flex 4 and code generated by Flash Builder.

Perhaps I can help translate:

thanks for the quick reply, but his issue is diffent from mine. The difference is that the application works, but like once or twice a day I would get that error. I have about 10 users max logged on to the application.

Well I know that I get some errors now and then with several projects. I guess these are sometimes related to communication errors and have nothing to do with problems in the applications (People closing browser tabs before the information was processed and therefore the response of the server could not be sent ... the Request was aborted before all data of the HTTP Request was sent, ...). Are you just trying to clean up your logs or is this a real problem?

Sometime its gets bad enough that I have to reset the application pool. I do not get any errors in the event log.

I have 2 version for this application:
The old version is based on Flex->XML->PHP->MSSQL and I have never experience this issue on it.
The new version is based on Flex->Zend->PHP->MSSQL.

Well I have to admit that I have never used Zend as I'm a Java guy. I would immagine that the protocol used by communication with zend is more vulnerable against disturbances than the xml format.

You say you have to reset the application pool ... is this something like restarting the webserver to reset all applications?
