Q: What does the following error in my windows eventlog mean -
The description for Event ID ( 487 ) in Source ( Zend Optimizer ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: Unable to view file mapping, Attempt to access invalid address.
A: This means Optimizer can't set up the shared memory. you need to clean your windows temp dir, ensure that everybody has access to it, and remove ZendOptimizer files from there, then restart the webserver. Alternatively, you can just ignore it - shared memory is used only for limited-user scripts, so if you don't run those, Optimizer is OK without it.
- Zend Optimizer is used with php applications to control security to them.
- Typically issues occur when the system does not have proper security access to folders
