Intermittent partial page load issue

Tuesday 04 April 2006 3:23:08 am

Hi there,

We have been experiencing issues on a website we have developed www.ccbriefing.co.uk - its running on a dedicated box which has plenty of resources dedicated to php, accelerators etc.

Something we have noticed is that occasionally, without any particular pattern, when a page loads it doesnt load all of the page - instead it seems to have stopped at some point during the page load so you only have half or so of the page...

If you then try to refresh it stays the same. On a colleagues machine they may well see this page fine so we know the page itself is working OK.

Has anyone ever experinced this - is there a php config tweak to ensure that pages always get fully loaded?

Many thanks, Steve.

Hi Bertrand,

Thanks for the response.

Yes we're runnnig Apache 2 - before we start looking at down grading, are there any other fixes, or do we know why Apache 2 has this bug?

Kind regards, Steve

Paul, thanks for the feedback.

In our httpd.conf we have:

# prefork MPM
# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare
# ServerLimit: maximum value for MaxClients for the lifetime of the server
# MaxClients: maximum number of server processes allowed to start
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 20
ServerLimit 256
MaxClients 256
MaxRequestsPerChild 4000
</IfModule>

# worker MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule worker.c>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>

In the modules I cant see a reference to either worker mpm or prefork..? Our phpinfo can be found at:

How do you verify which mode your are running in? And if you have to change mode, is the only way to do this by recompiling apache, or can you just add the module and restart?

Thanks Kristoff.

If we have the prefork version running, are their any tweaks to alleviate the partial page load problems?

For what its worth, I ironically had exactly the same problem trying to view this thread the other day - no amount of refreshing brought back the full page, so I used another browser and it then loaded fine.

I've experienced this occasionally with the Ez site, anyone else?
