503 error

[aragorn-jungle]

Hi, I sometimes get this error on trying to access my site:
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

I´ve solved this problem by calling up my hosting provider and they "reset PHP" but they say it's got something to do with open processes.
CMSMS version 1.9.3
PHP version 5.2.13

Please help

Forgot to mention that the "reset PHP" solution is only temporary.

59 views and no suggestions? thanks anyway.

[Sigrid]

Same thing is happening to me:

File does not exist: /var/www/vhosts

... how did you solve it in the end?

Many thanks in advance

One of my sites run into a similar (?) error since I upgraded to CMS MS 1.10.1
mod_security is blocking sometimes access to certain pages while in admin mode.
In the http error log files the same Atomicorp signature is visible.

You can try to put SecFilterEngine Off in your .htaccess file but most likely this is not allowed by your ISP. Contact your ISP to see if they can put in a ruleset in mod_security.
(if you are sure that the security interception is invalid though)
