Run some tracer apps on your code...could be some wild loops of some sort?
Never the less, ZEND debugger with the module should do the job....it will
tell you which files/functions etc are running....nice tool to track
execution time etc...

Hi
I am running SuSE 9.2 (Kernel 2.6.8-24-default) with Apache 2.0.50 and PHP
4.3.8 (as an Apache module) on a Celeron 900 with 304MB RAM. This machine
is
used for testing. We have made some changes to our PHP application and now
what changes? DB related per chance? doing any queries on tables that are
not indexed properly? or maybe your app creates tons of objects? (in which
case you might look at being able to clone objects rather than init new
ones where possible).
the machine is having trouble serving the pages. Apache is occupying
almost
90% CPU usage.
My Apache log configuration is:
%a %b %H %r %>s %t %T %X
%a : Remote IP
%b : Size of response
%H : Protocol
%r : Request
%>s : Last status of request
%t : Time of request
%T : Time to serve
%X : Connection status after serving request
In the log below the last character after the timestamp indicates the
following:
X : Connection terminated before end serving request
+ : Connection might not be terminated
- : Connection terminated
As you will notice almost all the statuses is connection might not have
been
terminated.
The page having the heaviest load uses 5 simultaneous sessions - they
refresh every 5 seconds. Even with just one connection there are 16 Apache
threads running all occupying between 5 and 20% of CPU.
Does anyone have an idea of what I can do (short of recoding)?
TIA
Albert
