ANTS 7 crashes IIS

The profiler crashes IIS before any pages show up, then the app just hangs.

We'd probably need to see a mini-dump to understand why it crashed. There are a few ways to do this but we have an effective way with minimal configuration needed:

You can download a small debugger from us if you don't have Windows debugging tools:
ftp://support.red-gate.com/utilities/AutoDumper.zip

Extract all files to a directory,

Run

Cscript adplus.vbs -crash -pn <name of process>

(Or you could try

Cscript adplus.vbs -hang -pn <name of process>)

If more than one process exists by the same name, you can use -P <pid> instead of -pn (work out which process number to debug using Windows Task Manager)

This then dumps files to disk on a crash or hang trigger. If the files are very large, I can set up an FTP account so you can upload it to us.
Or you can often see the exception by loading the dump file in windbg.exe and running "!anaylyze - v")
