如何在openshift上解析PHP：执行失败：'control restart'？

Question

I have a PHP (wordpress) app on OpenShift. It was working very well, so it stopped to work. I tried to restart using the rhc command, but was impossible. The follows error was shown:

>rhc app restart php
Failed to execute: 'control restart' for
/var/lib/openshift/53feXX835973XX99XXXXXXX/php

I also tried to restart using scp environment: ctl_all restart But again, it not worked and the follow error was showing:

An error occurred executing 'gear restart' (exit code: 1) 
Error message: CLIENT_ERROR: Failed to execute: 'control restart' for /var/lib/o
penshift/53feXX835973XX99XXXXXXX/php

I tried to get a backup of my app using rhc save-snapshot, but the backup file always is generated empty (0kb).

And If I try to restart using OpenShift WebConsole I receive the follows error:

Restarting PHP 5.3 cartridge (Apache+mod_php)
Application directory "php/" selected as DocumentRoot
Starting PHP 5.3 cartridge (Apache+mod_php)
Application directory "php/" selected as DocumentRoot
Failed to execute: 'control restart' for /var/lib/openshift/53feXX835973XX99XXXXXXX/php

So, what do I do to solve?
