W3SVC and 1074 - CRM slow downs/stops requiring IISRESET

W3SVC and 1074 - CRM slow downs/stops requiring IISRESET

Post by U3RlcGhlbi » Fri, 11 May 2007 22:20:01


Hi all,

I've done some searching around, and it appears that we are not the only
site to have a problem recently with CRM performance slowing down - taking
upto 4 minutes to open Accounts/Contacts via the web-interface - usually this
occurs after approx. 24-48 hours.

This is always resolved with an iisreset, and we get the following event
error:

"Event ID 1074: W3SVC
A worker process with process id of '11384' serving application pool
'CRMAppPool' has requested a recycle because the worker process reached its
allowed processing time limit."

I've not found any fixes or decent workarounds other than restarting the
server, or issuing an IISRESET - which is ok but I didn't really want to have
a task to do this every night - it doesn't seem a reasonable solution to me.

We have 30 concurrent users on a single CRM 3 server with SQL 2000 Standard,
on a overly spec'd box, and having been doing some performance monitoring,
there are seemingly no bottlenecks with processor, main memory commit, SQL,
or network.

I presume the problem is between IIS and ASP.NET 1.1.

Has anyone got any tweaking for IIS/ASP configuration that might resolve
this - I was looking at worker recycle, etc. I've rarely done much tweaking
with IIS with other products like Exchange, etc. Or I see some people have
taken this to MBS support - is there any response/fix from MS?

Any solutions appreciated!
Steph

Hi Stephen,

You can try to change the IIS worker process settings: in IIS Manager open
the CRMAppPool (in the ApplicationPools node). Open the properties dialog
and try if changing these values solves the problem. A description of the
options is available at
http://www.yqcomputer.com/

Maybe unchecking the "Recycle Worker Processes" and "Shutdown Worker
Processes after being Idle for..." helps, but I'm more a developer than an
administrator. Also download the "Optimizing the Performance of Microsoft
Dynamics CRM 3.0 White Paper" at
http://www.yqcomputer.com/

Hi Michael,

Thanks - will give some bits a whirl - and cheers for drawing me to that CRM
optimizing performance paper - must have missed this.
