    I have encountered an issue on one of the server today of having problems to load the Zend Optimizer after upgrarding PHP from 5.0.2 to 5.1.4 with MySQL 4.1.19. When I attempted to restart the Apache via the SSH , I am getting the following:

    This happens on all Zend Optimizer 2.6.2, 3.0.0 and 3.0.1 versions. However, the php -v do output the Zend Optimizer on the SSH but phpinfo() does not shows the Zend Optimizer being loaded.

    The issue is due to the Versioning modules in PHP. I have recompile PHP 5.1.4 without the Versioning support and reinstall the Zend Optimizer 3.0.1 and viola, both php -v and phpinfo() loads the ZendOptimizer properly now.

    Hope this may be benefit to those that are having the same problems.

    Great bit of info, thanks!

    I ran into this problem and really didn't expect it from PHP 4.4.4, but it is a paravirtualized server on FC5x86_64 as a DomU with FC6x86_64 as the Dom0, and this was the last little bit to have cPanel fully opterational in a DomU, couldn't seem to get more than 6 hours of uptime out of an FC5 i386 HVM under good load in cPanel.
