My website is entirely down, when access through the browser, the error message is
"Resource Limit Is Reached". When I check with the hosting provider, they told me the
entry processes is reached the limit of 20/20.  So I ask them to check which php processes
keep running and they found out that

The error logs are mentioned below:-

[Mon Jan 28 09:10:53 2013] [error] mod_hostinglimits:Error on LVE enter: LVE(530) HANDLER(fcgid-script) HOSTNAME(www.mydomain.com) URL(/piwigo/index.php)

An application piwigo photo gallery is utilizing most of the resources, due to which your entire site is down.

URL: http://www.mydomain.com/piwigo/index.php

Then I check the piwigo main directory error log.  I found this.
