Hi,

ypu have to Use the Debug Diagnostics tool and after that create the application pool for the website.

Thanks Abs!

I have downloaded and installed the Diagnostics tool. I have also configured to get 10 dumps. but, i am not getting any dumps saved automatically. but still the re-cyling and 1011 error thrown.

How do i get the dumps by automatic, whenever the crash happens?

Thanks in Advance

What application is running with PID 11624 on your server? This should be the process ID of the executable that's having issues and finding this will give more insight into a way to fix the problem. You can use the "tasklist" command to get a list of all running executables and their associated PID.

Thanks Camp,

The PID 11624 is the W3WP.Exe, which i have configured to monitor for crash in the dianostic tool.
But I am not getting the crash dump. As I have checked with MSDN, all the settings are seems to be correct. Also I watched DrWatson, that also does not have any dumps.

Now, how do i get the dump, whenever the crash is happening

Thanks in advance

Thanks Camp,

I got the dump and analysed.

Found out a very innocent and idiot problem. ie, In the xslt render, a Recursive function was called, which is not ending for certain records out of thousands of other records.

Finall deleted all the looped records in the database, and the recursive xslt is ending properly.
My site works very proper.

The statement of WANG, is very correct, "infite loops" in the code, kills the App Pool.

Thanks all for your time.

Well, that would certainly do it, and it happens to the best of us more often then we'd like to admit! Glad you're issue is now resolved, if you're all set please go ahead and close this question.
