dllhost.exe memory issue

I have the forum installed in IIS.5 and it opens an instance of dllhost.exe whenever the forum is accessed. The dllhost.exe file does not unload when the forum becomes inactive. It tends to increase its memory usage the longer the file stays open or as the forum becomes used more. In order to free up the memory I have to close the dllhost.exe process in Task Manager.

Is there a registry or IIS tweak I can use so that dllhost.exe closes or frees up the memory when the forum becomes inactive? I ran a second copy of the forum for test purposes and found that if you have more than one forum running on the same server, you get a dllhost.exe process opened for each forum. If you leave the processes running long enough, it can tend to use up a lot of cpu or memory resources needlessly.

2nd Question:

I think the WebWiz forum package rocks, except for the above mentioned problem. I purchased my copy this past December and just downloaded the newer version. Can I upgrade to the newer version without losing my current registration and message data? I'm thinking that as long as I leave the Access2000 database intact I should be able to upgrade without losing anything. However I'd like to make sure before proceeding. And will my original Link Removal code work on the new version?

Thanks!

dllhost.exe has been known to act up like that - usually due to some coding problem involving a DB, but for other reasons as well. It would probably help if you upraded your version. I haven't seen this behavior in WWF however going back to V6.something. Do you have any mods installed?

There's also a virus version of dllhost which is fairly common. You may want to do a system scan with your AV program.
