gator53 pre.php warning?

[Sirkent]

Hi,

I'm on gator53.

Intermittently (but it happened about 5 minutes before this posting time) all of my websites display a warning:

Warning: shell_exec(): Unable to execute '/bin/hostname' in /usr/lib/php/pre.php on line 8

This seems to happen every few days at random times and for random lengths of time.

This obviously comes before any headers and therefore prevents my websites from operating properly. The websites also become very slow during this period.

Does anyone have some sort of idea as to what could be causing this, how to fix it or how to prevent it?

Would it be possible to simply turn the warnings off? I'm not sure if this would solve the problem of the websites operating slowly...

Thanks,

Sirkent
