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.
- 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.
Sweet…thanks!
