ASP is running really slow on my IIS Windows 2003 setup. I restart IIS and then it is fast again. But very quickly it degrades and sites using ASP are very slow to display in my browser.
I checked the event log and found a day or so ago that there were alot of SMTP errors similar to this one.
Message delivery to the host '126.96.36.199' failed while delivering to the remote domain 'torfree.net' for the following reason: An SMTP protocol error occurred. The SMTP verb which caused the error is 'HELO'. The response from the remote server is '540 <ironclad-429eg1>: Helo command rejected: Host not found '.
I'm wondering if maybe someone is running a script that is sending spam. However, I'm not sure how to track something like this down. Any ideas? Is there a way to view running ASP processes to see if there is one that's causing the slowdown?
Viewing the task manager doesn't show anything. I only have like 9 processes showing up under the Processes tab and the CPU usage is low too. I don't see anything there to alert me to a problem.
As a followup here, is there some utility or program I can use to monitor the processes that IIS is running? I saw reference to a file called iisstatus.dll in one thread here back in 2003 and on another forum someone mentioned it. I can't find anywhere to download that file.
So, is there some method anyone can recommend? My ASP is running real slow again. It is fine if I use the 'iisreset' command, but then quickly degrades again.
Thanks. I was able to find IISTRACER yesterday and get it installed. I do see the output of the program in the browser window but am not sure what I'm looking for. I see each line is a request for a web site resource of some kind and I'm guessing I'm looking for ones that have very large numbers.
Here are the columns I'd like clarification on, as the directions seem to be kind of vague.
In the Running column, I have over 50 entries right now. Most of them have 6 digits, while 2 at the top have 7 digits (over 1 million). What should I be looking for here to discover problems?
