KMcDermott -> ASP app Hangs after upgrade from NT4 -> Win2000 (9/21/2004 15:29:06)
|
I moved this from another forum, as it seems to be more appropriate here:
I have a .asp application that ran on my site without interruption when it was running on an NT4 server (IIS4). After moving the site to a new ISP and Win2000 server (IIS5), it randomly stops responding on the site. Have to go into the server and restart IIS for it to come back up.
I found this, and thought it was my problem:

from Microsoft Knowledge Base article 821749 (http://support.microsoft.com/default.aspx?scid=kb;en-us;821749):
SYMPTOMS
On the server that is running Internet Information Services (IIS), the IIS Admin service may stop unexpectedly or crash, and your antivirus software may report that your computer has been infected with the Code Red worm even though you installed security updates to help prevent this worm. The following error messages may be logged in the System event log:
Event Type: Error
Event Source: Service Control Manager
Event ID: 7031
The IIS Admin Service service terminated unexpectedly. It has done this X time(s). The following corrective action will be taken in 1 milliseconds: Run the configured recovery program.
Event Type: Error
Event Source: Service Control Manager
Event ID: 7031
The World Wide Web Publishing Service service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 0 milliseconds: No action.
CAUSE
This problem occurs because the antivirus software detects Code Red worm requests, including .ida file requests, to the World Wide Web Publishing Service. The antivirus software acts as if the server has been infected with the worm, causing the IIS Admin service to crash or close unexpectedly.
This problem can occur with McAfee antivirus software that is running a signature before 4266.
RESOLUTION
To resolve this problem, contact your antivirus software manufacturer for an updated signature file. If you are using McAfee antivirus software, update the signature to 4266 or later.
I had old McAfee sigs running and was getting those exact errors. Updated to preferred levels, but still get the random crashes.
I say random, but they tend to be late at night/early morning, and on the weekends, when presumably server load is quite low.
There's an XML that runs every 15 minutes to monitor various spots on the site, and it has reported back "NOT RESPONDING" on the same ASP app every time the crash occurs, so I can only assume that there's an issue with that app. Is there an ASP service log that I can check?
IIS Debugger lists CONNECTION_ABANDONED_BY_INETINFO_CRASH as the s-reason
Only other similarity I can find, is that an EVENT ID 4 ASP SERVICE HAS STOPPED usually precludes the hang/crash.
I've also seen some EVENT ID 4097 MS DTC HAS STARTED and EVENT ID 4156 Session Idle Timeout - Tearing down Session. I was under the impression that MS DTC was specific to NT4, and on 2K COM+ was the rule... mind you I'm in NO WAY versed in ASP/.NET/COM+ applications, so that's only from what I've read.
I've been pointed toward installing IIS5Recycler as a workaround to restart IIS automatically so no interruptions in service, but want to FIX it.
Apparently IIS5Recycler has some "advanced scripting features" to address/document memory leaks... anyone familiar with configuring?
What else can I look at?
TIA
Kevin
