The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Debug Diagnostic analysis

Asked by brij_rauthan in Debugging Software for Development, Computer CPU Processors

Tags: COM+ Dllhost.exe high CPU utilization

Hi

We have a website and over a period of time, CPU utilization goes 100% and almost everything is being eaten by DLlhost.exe. I used DebugDiagnostic to anlyse the problem, and found that some objects are not being cleared. I disposed explicitly in the code, still having problems.

Can someone help:

Following is excerpt from Debug Diag:

The COM+ STA ThreadPool may have been depleted prior to the time of the dump in dllhost.exe__P41__PID__3736__Date__07_31_2009__Time_05_02_13PM__828__Manual Dump.dmp. The pool has grown to its maximum allowable size, but some threads do not currently have any activity bound to it.
