IISSTATE - Please help with log analysis

Hi there,

I'm running a windows 2000 Advanced server machine, with several .NET
applications and websites running.

Over the last few days we've been experiencing hangs on the ASPNET_WP
process for ASP.NET version 2. When it hangs, the version 1 sites can
be visited fine, but I can't PCAnywhere onto the server to reset the
process, so I need to reboot the machine.

I've put the IISSTATE logs here:

http://www.remote.uk.com/iiscrashlogs/

Would someone please help me and give me a clue as to what might be
causing the problem?

Many thanks in advance,

Paul McGillivray

Well...

The good news is that there were no hangs that I saw - only crashes. They
appear to be happening in multiple places:

front.product.Page_Load

front.c_leftcontent.setImageSubHeader(String)

Most likely there are some parameters that are coming in NULL that are not
being checked. If you enable debug mode on the site you'll probably get
more info for fixing the code.

Hi Pat,

Thanks loads for checking that out for us; we're looking into the code
you've flagged up now; strangely though, when we run the pages that
use that code, they're running fine and the server's staying up; we've
noted that we're serving up large files as part of a document server
though, and whenever the file is larger than 4MB, the server's going
down then.

Is it possible that the file server is crashing IIS, and that those
bits of code you've pointed out just happen to be running at the time
of the crash?

Many thanks,

Paul

Nope. Those codes were throwing Access Violation exceptions. It could be
that something else is going awry that is causing the pages/codes to fail.

OK, thanks Pat, we'll track them down.

All the best,
