Out of process application '/LM/W3SVC/1/ROOT' terminated unexpecte

Hi all, I'd appreciate any help on this one;

We've built a Web server with Win2K Adv Server with IIS. All looks fine and
has been tested (although hard to recreate the amount of traffic that a live
server takes) before being put into live. We then join it to our live web
cluster (using NLB, feature of Adv Server). Again all looks ok, then after an
hour of being in the cluster, IIS starts to crash, with multiple restarts
occuring and '500, Internal server errors' being displayed to any visitors,
can see this in the W3SVC1 logs.
I've looked at various articles for why 'Out of process errors' can occur
but there seems to be various reasons, obviously depending on what the server
is used for and what is installed. This particualr server has SP4 applied and
all Windows Updates upto 10/03/2005. The server runs one website and using
ASP applications and also using a couple of dll's we have created to write to
certain logs. When IIS crashes we get this error in eventvwr;
Out of process application '/LM/W3SVC/1/ROOT' terminated unexpectedly.
You get the usual HTTP 500 Internal Server Error page if browsing to the
site. If you go to Tools, Internet Options and uncheck the 'Show friendly
HTTP error messages' in the Advanced tab, you then get the error;
The requested resource is in use.
I'm about to try and use the IIS resource kit to find what is going on, but
if anyone has any other ideas or in out, it's be much appreciated.

Thanks, Colin.

The error in the event log is pretty generic. You can reproduce both the
event log error and the server 500 error simply by killing the dll host
associated with your website.

Something in your web application is causing the dll host to fail. We have
1 3rd party application that is particularly troublesome. It has a memory
leak and when the dll host reaches about 1g of memory usage we start to have
odd problems. At that point we either kill the dll host or we reboot the
server.

Check your dll hosts in task manager and see if you can isolate the problem.
I you suspect a particular dll or application you can use a process explorer
to give you more insight into what's going on inside the dll host.

Can you get an IISState log please for us to look at?
