It should not be related to the application pool. I have 1740 minutes as the
recycling period and I do not see any records in the Event Viewer. The
application is not restarting. I have http module that catches AppInit events
and sends me an email notification every time the web application starts.
Actually I tried to add objects to the cache using CacheItemPriority.
NotRemovable instead of CacheItemPriority.High and in this case objects stay
in the cache. This would happen if I do not have enough memory, but according
to Task Manager I have 500MB of available RAM + 3GB of system cache that I
believe should have lower priority than the ASP.NET cache.
BTW does anyone knows whether the ASP.NET cache has really higher priority
than the windows system cache? I have another application running on my
server that is constantly reading a few files per second. There are millions
of these files. Maybe Windows just grabs all the resources for the disk cache
and makes ASP.NET clear its cache?

long time ago that would scan my web.config and restart my application every
so often.
