CakePHP 2: Intermittent Fatal Error prevents application from loading












0















I'm experiencing a strange recurring error in my legacy CakePHP application. At odd times, I'll see the following error in my error log:



Fatal error: include(): Cannot redeclare class <classname> in /lib/Cake/Core/App.php on line 522


The classname varies, but the ones I'm seeing lately are connectionmanager, Debugger, and set. My site goes down for anywhere from a minute to half an hour, then magically starts working again. The Fatal errors disappear from the log, and everything's back to normal. This started about three weeks ago. There doesn't appear to be any kind of pattern, and the code has not been significantly altered in the three weeks since the problem was first reported.



I also have two other sites on the same server, with the exact same source code, only with debugging turned on. I'm not seeing this problem in either of those sites. The only difference among them is the site that keeps dropping out is in use by several people during the day.



Application is running on CentOS 7 with PHP 5.4, MariaDB version 5.5.6. I also saw this problem before we migrated away from our CentOS 5 server.
