Symfony – does not have a registered handler / out of free disk space

Last night I started getting down time alerts from New Relic on our Symfony based Application. Our production server went down and while investigating PuTTY started giving us a error similar to:-

PHP Warning: file_put_contents() : Only 0 of 36492 bytes written, possibly out of free disk space in /usr/lib/php/framework/symfony/lib/autoload/sfSimpleAutoload.class.php on line 165

Looking into message a little closer I found that the server had ran out of disk space so after making some space and using “symfony cc” to clear the cache i thought that this would have resolved the problem, however i continued to get below message “does not have a registered handler” being presented.

Fatal error: Uncaught exception ‘sfConfigurationException’ with message ‘Configuration file “/usr/lib/php/framework/symfony/config/config/settings.yml, /home/portal/www/site/apps/frontend/config/settings.yml” does not have a registered handler.”

After investigating closely I found the cache was not cleared properly even after running ‘symfony cc’. At the end, i had to clear the cache manually with below command :-

rm -fr cache/*

For some reason this seemed to work fine where as the “symfony cc” command didn’t work therefore the only conclusion that I could come up with is that when the server ran out of disk space it corrupted something in the symfony cache which either is not normally cleared with a “symfony cc” and as a result i needed to remove it completely so symfony could re-build it automatically.
