Not sure if it is mySQL server that is causing the issue or what not... but clicking on specific links in cpg always makes my server load go to 100% and does not come back with the page it should...  For example if I click on Admin Tools the mySQL server takes up all the cpu ... the cpu goes down after about a minute or so...  

The page comes back with maximum execution time of 30 seconds exceeded in functions.inc.php on line 79 and partial page is only displayed...

Any suggestions/ideas?

hmm... vbulletin is known to be resource-intensive. What kind of links cause this behavior?

[jarekn]

Hello,

For example if I click on Admin Tools the mySQL server takes up all the cpu ... the cpu goes down after about a minute or so... 

The page comes back with maximum execution time of 30 seconds exceeded in functions.inc.php on line 79 and partial page is only displayed...

hmm... vbulletin is known to be resource-intensive. What kind of links cause this behavior?

[kegobeer]

If you are running your own server, perhaps a misconfiguration is the root of your problems.  Since this is not normal behavior for Coppermine to consume 100% of CPU cycles, I would verify your installations are correct and optimized.

There are a lot of resources available for server setup.  Whenever I run into server problems, I Google for specific forums (PHP, Apache, Windows, MySQL) and see if there's a solution for my particular problem.

[donnoman]

Yah something for sure isn't right. I run my development install's from coppermine 1.2x to 1.4x on a windows 2000 iis5 server with a celeron 500, and 128mb of ram, and I've never experienced that.

calling up the admin tools page doesn't use much resources... unless youre really talking about that you told the admin tools to oh say, recalculate all your thumbnails. Then yah, your server would hit 100% util because of invoking imagemagic or gd to do the image manipulations.  These are resource intensive and will use all the cpu cycles they can lay thier hands on until they're done.

[jarekn]

I know what you are saying about calling up the admin tools page ... and no it is not using any of it functions but just calling that page on its own...

I have couple of the same slow downs with PHP New Ads... clicking on some of the options just makes the SQL go nuts...

Anyone else using 4.0.17?  What is the best/most stable version to use?

[kegobeer]

I always go for the latest stable releases, MySQL 4.1.12, PHP 5.0.4, Apache 2.0.54 (or the latest IIS if you prefer).  I always do my own installations and never rely on any WAMP package to do it for me.
