Cache Issues in Asp 2.0

SteveF

When running an Asp.Net 2.0 web application
any items that I add to the cache are being removed almost instantly
with a reason of underused. I know this as I have hooked up a delegate
that is invoked when the cached item is removed.

If I set the priority to be NonRemoveable this does not happen however
this leaves the application in danger of taking up large amounts of
memory and is not really an 'workaround'.

Anyone else seen or heard this problem????

This is probably due to having too little free memory. The server will
throw away cached items when it needs to free up more memory.

I have experienced this problem since upgrading to 2.0. Others have
commented on it elsewhere. I don't think this is simply a problem with "too
little free memory".

In my case, there are times where objects inserted into the cache instantly
disappear. This does not seem to have any correlation to the amount of free
memory on the system.
