Zend Opt 3.3.0a installed, produced watchdog cron errors - why?

[jjsba]

We are running PLESK 8.2 on CENTOS 4. Today we installed Zend Optimizer 3.3.0a on our server and all seemed to take well, php -v is reporting:

[root@www src]# php -v
PHP 4.3.9 (cgi) (built: May 10 2007 05:19:09)

But tonight, during the cron processes, the following errors were reported by the watchdog program:

FIRST ERROR:

From: Cron /usr/local/psa/libexec/modules/watchdog/cp/clean-sysstats
Error: Failed loading /usr/lib/php4/php_ioncube_loader_lin_4.3.so: /usr/lib/php4/php_ioncube_loader_lin_4.3.so: undefined symbol: zend_hash_add_or_update

SECOND ERROR:

Error: Failed loading /usr/lib/php4/php_ioncube_loader_lin_4.3.so: /usr/lib/php4/php_ioncube_loader_lin_4.3.so: undefined symbol: zend_hash_add_or_update

ERROR THREE:

Error: Failed loading /usr/lib/php4/php_ioncube_loader_lin_4.3.so: /usr/lib/php4/php_ioncube_loader_lin_4.3.so: undefined symbol: zend_hash_add_or_update
/usr/local/psa/admin/bin/php: symbol lookup error: /usr/local/Zend/lib/ZendExtensionManager.so: undefined symbol: zend_get_configuration_directive

Anyone have any thoughts or ideas on how to fix this problem? There has to be a way to get Zend Optimizer 3.3.0a working well with PLESK 8.2!

Any advice or input would be GREATLY appreciated!

Thanks,
