500 Internal Server Error - Frustrating!

Hello folks,

I'm hoping someone can help me with following error which I keep getting when trying to access my website:

I have contacted my Host who have said my website is using too much memory (I was allocated 512mb) and said I should optimise my website. It is a WordPress based website and I have W3 Total Cache installed to try and minimise the memory used. There are only 3 pages on the website so I don't understand how it can be using so much memory.

My error logs looks like this:

and I have thousands upon thousands of these errors in the log file.

My host has increased my memory to 756mb and that solved the error for half a day, but I'm back to square one again.

I would really appreciate some help to solve the matter.

Thank you.

 

Those errors likely aren't due to you running out of RAM.

Try this: http://www.somacon.com/p520.php

That said, if you are indeed using over 756mb of RAM though, that is entirely inappropriate for shared hosting. When you start approaching 1GB of RAM usage on shared hosting (especially since your account does not include the OS, cPanel, etc.) it's time to upgrade to a VPS.

 

Thanks for taking the time to reply.

I've just been contacted by my host who said they fixed the error and it was due to memory depletion. No further explanation was given so I'm not entirely sure what the problem was.

 

I used to run lighttpd on my vserver and the php was slowly leaking memory. Eventually I switched web servers and the problem went away. As long as your using normal scripts up to date its usually your hosts fault.

 

That's not true at all, unfortunately. It's usually WordPress plug-ins that cause memory issues like this, up to date or not.

 

from the imagick error logs, it's probably from a plugin that image related like generating thumbnail. try disable that plugin and see if you still getting error message

 

How many pageviews and bandwidth usage are you seeing daily? Imagick is a php extension that can modify images--uses ImageMagick. Have you tried an upgrade or clean install of wordpress? You can do this through FTP and then rebuild the database without affecting your themes/data.

 

Since you're using w3tc you can try disabling the minifying option and use this plugin Better WordPress Minify to do the minifying and sometimes a 500 error can be caused by a corrupted .htaccess file .

 

"Module 'imagick' already loaded in Unknown on line 0"

You are running a crap plugin, that is what your issue is.
