w3svc event 37

I'm getting these warning messages in the system event log (win2k, iis5.0):

Event Type: Warning
Event Source: W3SVC
Event Category: None
Event ID: 37
Date: 09/04/2004
Time: 00:41:40
User: N/A
Description:
Out of process application '/LM/W3SVC/1/Root/[application name]' terminated unexpectedly.
For additional information specific to this message please visit the Microsoft Online Support site located at: http://www.microsoft.com/contentredirect.asp.

The message comes up several times within the space of a few minutes and then IIS stops responding. Then nine times out of ten I cannot even restart IIS to get it going again: the www publishing service freezes on "stopping" and the only way out of it is to reboot the server.

It's happening on a freshly built, fully patched machine. (On an older server the w3svc warnings were often followed by a WAM error (event id 5) which ultimately also caused IIS to freeze.)

I've searched the MS knowledge base with no luck. Has anyone else seen this message before? Any ideas what causes it?

Any help greatly appreciated. This one's causing quite a headache as it occurs so often.

Bad application code can cause IIS to terminate. If you moved your asp application to the new server perhaps you moved the problem along too.

MS has this asp troubleshooting guide for W2000, maybe something in it will help you out.

Ok, thanks.

Presumably the steps in the troubleshooter need to be followed in a period when IIS is hanging? The problem happens so unpredictably it could be a couple of days before I get to try it.

I am getting

Out of process application '/LM/W3SVC/1/Root/projects' terminated unexpectedly.

from w3svc Event ID 37

The problem in my case is that all .asp pages fail to load with a "The Remote Procedure Call Failed" message in IExplorer.

This happened suddenly 2 days ago to a server that has been running fine for 8 months. I transfered the Application to another iis server and it works fine.

I am w2k sp4 iis 5

Help! please!

There is some server problem, you'll have to troubleshoot the server. I doubt it is an IIS-specific problem, probably something else failed on the server is my guess.

I have been around it and reinstalled iis check the sql connection I am at a loss?

Was there ever a resolution for this? I seem to have come across the exact same issue. We are operating a site on a web farm of 5 servers, and it appears to be happening on all the servers, which suggests an application problem to me.

I would be grateful if anyone could share what the resolution was.

Hi, I'm back with an update. We're still getting the error, but it has decrease in frequency and likelihood of causing ASP freeze-up since we had a custom DLL upgraded by our supplier. Since then, we have been getting freeze-ups roughly once a week, and just putting up with the reboot. I've been taking another look at it recently because we're running a new app on the server, with a lot of users who get mighty annoyed if the system goes down.

Further googling has pointed me in the direction of possible memory leaks, and using iisState.

What I have done (a couple of days ago) is set each important app to high isolation so they run in their own dllhost, instead of the "Out-Of-Process Pooled" one. This way, I should be able to track down which app(s) is(are) the root of the problems. Since then, I've had only one w3svc event 37, but memory usage has been creeping up.

Does anyone know which Performance Monitor counter(s) can be used to track memory usage per process? At the moment, I'm sat checking task manager every couple of hours.
