[users@httpd] Really annoying problem either with Apache2 or PHP or both

[David Wills <mishy.cth@xxxxxxxxx>]

Hi,

I am having a really bad time with apache 2 and have been for months now. I have tried everything I can think of to 

rectify this and its just not working.

I am having gigantic 30second page load pauses with Apache2. These appear to be random but its hard to tell if 

there is a specific cause as my server is quite busy. Users complain, and it drives me absolutely crazy.

The only thing I can see in my error_log that coincides with these incidents is this:

[Sat Sep 10 04:39:00 2005] [info] (104)Connection reset by peer: core_output_filter: writing data to the network
[Sat Sep 10 04:39:00 2005] [info] (32)Broken pipe: core_output_filter: writing data to the network

I don't know if this is a clue or not but there also seems to be 404s around the same time as those errors pop up 

^^

I get hundreds if not thousands of those per day. This is not someone just hitting stop of their browser. That 

explanation does not fit the sheer number of occurances at all. Again, I would like to reiterate that this has been 

going on for months.

Can anyone help me please - its getting to the stage where I am just going to switch from apache to another 

webserver or downgrade to 1.3.

Thanks for any offers of help - I really am getting so frustrated.



What I have tried:

i) Removing completely unnecessary modules
ii) Tried removing necessary modules one by one to see if that improved the issues.
iii) Upgraded from PHP 4.4.0 to PHP5.0.5
iv) Disabled my firewall
v) Disabled mod_security
vi) Asked at my data centre to see if they had a problem on their end with either my server or its connection to 

their backbones
vii) Removed eaccelerator
viii) Removed Zend Optimizer
