w3wp.exe high CPU usage
Mat
I am using MOS 2007 for our intranet & since last Thursday have been
experiencing very slow performance on all parts of the intranet.
Basically when the intranet is called "w3wp.exe" spikes up to near 100% &
the page slowly loads, when it has loaded (10 seconds) the process goes back
down to normal.
Then when another link is clicked, bang straight back up to near 100%. This
is causing me a major headache as nearly 300 users have our intranet set as
their default home page so as soon as internet explorer is opened the CPU
usage is going through the rough & as you can imagine throughout the day
many people are opening & closing IE.
I had this problem many months back but releated to a specific workflow on a
site section (no enough steps) this was isolated as the spike only happened
when the workflow was started, but now I can't really pin point to what line
of code or whatever is actually causing "w3wp.exe" to go mad.
I have asked the developers to revert any changes to the master page etc
back to when it started working & they are assuring me that nothing has been
changed.
Only one thing I would like to add is in the application event log at around
about the time it started happening i saw the following events ;
ID : 7043

I am also now getting loads of different 7043 errors for different
controltemplates & also the following very interesting ASP.NET ID 1309 error
;

If any one could point me in the right direction I would greatly appreciate
it.
