Annoying "white page" when accessing web applications

[niedermayer]

Hi,

I'm running some web apps on a shared hosting plan, includes phpbb3 and cmsms. The problem I have is that the at random times users gets a white page when the page has finished loading. What I've seen is that in my transfer log the number of bytes are not returned when users access the page. The http status code from such a response is 200, so the request is valid.

The transfer log spits this out:
xxx.xxx.xxx.xxx - - [12/Jun/2009:20:39:18 +0200] "GET /forum/viewtopic.php?f=16&t=153&view=unread HTTP/1.1" 200 - "http://www.domain.com/forum/viewforum.php?f=16" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)"

Instead of this:
xxx.xxx.xxx.xxx - - [12/Jun/2009:20:39:18 +0200] "GET /forum/viewtopic.php?f=16&t=153&view=unread HTTP/1.1" 200 [Num of bytes] "http://www.domain.com/forum/viewforum.php?f=16" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)"



Any ideas whay may be causing this, or how this can be debugged in order to figure out the cause?

Hello,

GET /forum/... isn't CMSms specific. There may be nothing wrong with your CMSms install along the forum one. You may gather better responses from the forum support (they know their product better than us) and the hosting support (they know their shared hosting overloading better than us).
Happy debuging
