I have a Windows 2003 Server Web running 5 web sites. Every few days, the
ASP pages stop responding. There are no events in the event log. The HTML
pages are still served successfully. These pages have no database
interaction (others use MySQL). I have to restart IIS in order for the pages
to work again.
I haven't been able to find anything about this issue on the web. Has
anyone seen this before? Any idea how to fix it?
Thanks. 7 2323
It could be some odd problem which hangs the application process. I've
experienced something similar on my testing server...
in my case it was because of Norton AntiVirus whose ScriptBlocking was
causing the process (an instance of dllhost.exe run under user
IWAM_machinenam e) to hang at 100% CPU everytime a page tried to access
FileSystemObjec t methods. The only solution in this case is to disable the
ScriptBlocking feature (if FSO is really needed) or to replace
FileSystemObjec t calls with calls to ADODB.Stream, which doesn't (much
strangely) get blocked. I've heard that also McAfee Viruscan has a similar
function, which causes similar problems.
Otherwise... you should just check if there might be a conflict with any
other software installed on your server.

I'd suggest you study the IIS logs to find if it is related to just one ASP
page. Then put in oodles of error checking and/or write you own text log on the
server. At a minimum, write an entry for the entry and exit of the ASP code.
Then, when it does fail, you have your own log to tell you what is going on.

Thanks. I'll make a note to check the server load the next time this
happens, although I don't recall any slow response times when poking around
looking at logs and event viewer records. The server is running McAfee. I
don't know the code well enough to recall whether FileSystemObjec ts are used.
I'll look for that.
The server is pretty slim on software. It's pretty close to out-of-the-box
Windows 2003 Web. It ran flawlessly for about 6-7 months, and is now
problematic with no software changes, upgrades, installations.. .only MS
patches.

Put all apps on HIGH ISOLATION, then install Process Explorer from Sys
Internals and you can view each app and see what memory and CPU usage
it takes up.
I've had another occurrence of this situation today. During the incident, I
checked the 3 sites that use ASP, and HTML pages were viewable successfully,
but all ASP pages stopped working. The system usage was quite low (CPU
around 5-8%; memory: 450MB of 1GB).
I noticed one thing that has me doing further research. There was a process
named W3WP.exe that had memory usage of 380 MB. It wasn't actively using any
CPU time. After restarting IIS, the memory usage reset to about 30 MB, and
now after about 3 hours, it's back up over 100 MB again and climbing. Does
this sound right?
Since I'm running IIS 6, I believe that by default the apps run in High
Isolation. I'm at a loss regarding how to fix this. Any other ideas that
come to mind?

Larry, what does Process Explorer display that isn't available in the task
manager? The interfaces and information look very similar.
Sorry about the duplicate posts. I guess the error message about expired

We have a web application running on Win2000 AS/IIS 5.0
Developed using ASP (not ASP.NET), this is set up to run
in a medium (pooled) memory space. (DllHost.exe)
After installing .NET framework 1.1, any request to any
of our .asp pages makes DllHost.exe to start, and then
hang. No response on the client.
Anybody experienced this problem, or have any hints?

I'm observing the following:
If I commit the following records 1,2,3,4,5,6,7,8,9,10 to the database
and the server hangs, I could lose records 5,6,7,8,9 but record 10 is
there. How is this possible and do anyone know how Postgresql
physically writes the records?
Thanks,

Help,
I'm not sure what exactly is happening but I can say this, classic asp
pages are not loading on my local dev box. They use to work! Since
then I have installed .NET 1.1 Studio (that is working, and so is ASPX
pages), installed .NET 2.0 Studio (this never worked, it broke
everything, ended up reinstalling 1.1 Studio, and now I am back to ASPX
pages ver 1.1 serving up nicely). However!!! Now I can not run classic
asp pages.
