DW20.exe process causing slow SalesLogix web deployment and testing

I recently experienced a problem on a test development environment where the SalesLogix web site I was working on was experiencing slower than normal performance.  I noticed this especially after frequently re-deploying the site to troubleshoot some problems.  Now in this case I had been doing my development on an Application Architect instance on a workstation and then deploying my web site to another server.  I decided to take a look on the web server and see why the site performance would be so poor.  I discovered that the DW20.exe process was maxing out the CPU and preventing the w3wp.exe from doing its thing in compiling my ASP.Net pages.  DW20.exe is a Windows process for error reporting.  See this KB for details.  This posting also points out how to disable the process by modifying registry keys.  After doing this I was still having the issue though.  I discovered that there is a way of turning off this error reporting through a Windows management interface.  All you need to do is:

  • Bring up Control Panel.
  • Open System
  • Go to the Advanced tab
  • Click the Error Reporting button.
  • Choose the Disable Error Reporting.

Disable Windows Error Reporting

  • Click OK back out.


After that the process disappeared, and the CPU was freed up for use on building my web site.  I would think it is probably a good idea to turn this feature off in a development environment, as you are likely to be producing the kind of problems the error reporting process is likely looking for.  I am not sure what point the process goes crazy but if you run into it, hopefully this post will help out.
