Cannot allocate Memory Issues

[digitalmick007]

Hello All,

I've had a on-going issue with VB5 for ages now since upgrading from VB4.

Here are the specifications on the site

1. vBulletin Version - 5.3.2
2. PHP Version - 5.6.31
3. MySQL Version - 5.5.55-cll
4. Any Addons installed - Tapatalk, Quarto VB5 Theme (latest version)
5. Web Address - www.zeitakuvip.com

So the issue i'm facing is the site randomly isn't loading pages. I get a HTML 500 Issue and randomly image attachments are not loading.
When you click on a image attachment and enter the lightbox, all you see is NULL where the image should be.

Server logs are showing this style of error consistently. see example below.

This happens on all sections of the forum.

PHP memory is set to 2GB atm! (2000m)

Also randomly when you visit the forum, it wont load the theme correctly and you have to refresh the site multiple times. This happens on all styles and themes including the included VB5 default.

I never had this issue with VB4 before, but its now causing serious issues for usability.

Same here, any news about this issue?

This isn't a vBulletin issue, so there wouldn't be any 'news'...it is a server problem.

In order to point you in the right direction, please let us have the full, exact error message, and what you were doing on the forum when it occurred.

This error is coming from the server operating system, not vBulletin. It appears that your server needs more memory to allocate. It doesn't have enough memory to spawn new child processes in Apache.

If you're on a shared server with unlimited usage allowances, you could be sharing that server with thousands of other sites.
