Memory issues when PHP is running as suPHP

[sheringp]

I am getting this error when PHP is running as suPHP. It is OK when PHP is configured to run as DSO.

========================================
[Sat Oct 17 11:27:38 2009] [error] [client xxx.xxx.xxx.xxx] Failed loading /usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so: /usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so: failed to map segment from shared object: Cannot allocate memory
========================================

Could anyone please help me to find what could be causing this.

Any help in troubleshooting the problem is highly appreciated.

Many Thanks,
Sherin

What is your PHP version?

If possible, please provide the output from the following commands (via root SSH access):

# /usr/local/cpanel/bin/rebuild_phpconf --current
# /usr/local/bin/php -v
# /usr/local/bin/php -i | grep configure

Zend Optimizer has known issues with certain newer versions of PHP, including PHP v5.2.10 and v5.2.11; for better compatibility with Zend Optimizer a safe PHP version to revert to (via EasyApache) is PHP v5.2.9.

Several of our servers started giving the 500 internal server errors on all php sites. In the logs, the above error showed. The results of the commands are:

So you are saying that switching to 5.2.9 may resolve the issue?

 

[thewebhosting]

Please make sure that you have assigned 644 permission to your .php files and also make sure that there is no php functions assigned in your .htaccess file.

 

[ModServ]

Also check the size of suphp_log file located in /usr/local/apache/logs if it was 2GB then you should rotate it.

I would re-install Zend Optimizer; thee is a newer version that should work better with PHP up to version 5.2.12, as seen below:

# /usr/local/bin/php -v
PHP 5.2.12 (cli) (built: Jan 19 2010 17:10:33)

    with Zend Optimizer v3.3.9, Copyright (c) 1998-2009, by Zend Technologies
    with Suhosin v0.9.29, Copyright (c) 2007, by SektionEins GmbH

Here are two commands that may be used to remove and then re-install Zend Optimizer in PHP:

# /scripts/phpextensionmgr uninstall Zendopt
# /scripts/phpextensionmgr install Zendopt
