ASP Error Code 0246

[jasonastewart]

Running IIS6, Windows 2003 SP2.

I've got a single website with multiple virtual roots beneath it. These are named by the customer's state and act as a portal. for Example: mysite.com/ca mysite.com/wa mysite.com/nj etc.

Every few days one (not all) of the virtual roots will stop accepting incoming connections. IIS logs show ASP_0246 "TOO_MANY_CONCURRENT_CONNECTIONS".

The error seems to be localized to a single virtual root and does not affect the others. It does not consistently happen on any particular virtual root. In fact, this has never happened on the virtual root that actually has the most users. It seems random.

I've spent a lot of time and the only info I can really find on ASP 0246 is the list of error codes on the MS site and others...haven't been able to find any info about the best way to attack this problem. Can't find anyting in the metabase about concurrent users (concurrent connections on all virtual roots have been set to unlimited)

My questions are:
1. What does ASP think a "USER" is?
2. What is the limit (there has to be a limit or else there could never be "TOO_MANY", right?) ?
3. Is there a way to change this limit?

There is a limit to the number of connections that can be made to the web server. It doesn't have anything to do with the anonymous user or the ASP NET user.

There is a way to increase this limit. Check out this article about Configuring and administering IIS6. It's a long article so I suggest that you use the search functionality of your browser to search for "number of connections" to get to the section that you're most interested in.

I think that you may be experiencing too much traffic to your site. You may have to consider a different server configuration (ie a Web Farm or Web Garden) to handle the traffic.
