Magento and setroubleshoot causing certain pages to die.
Hold on Cowboy
This blog post is pretty old. Be careful with the information you find in here. It's likely dead, dying, or wildly inaccurate.
Some pages in Magento were giving just a white page, with no indication of errors in Zend Server console or log files. This was apparently a memory issue, so I restarted the web server and all was fine.
One issue I noticed was the server “setroubleshoot” was taking 12% of the systems memory. This program just logs issues with SELinux and it seems SELinux doesn’t like my Magento install. I have SELinux just set to ‘warn’, but I may want to disable it all together. I stopped the ‘setroubleshoot’ program and turned it off with chkconfig.
