I measured the Gen/0/Gen1/Gen2 collection counters on an instance of w3wp.exe and noticed that these counters decrease at some points. I would expect that by being accumulative counters they would never decrease for a single process. I had multiple instances of w3wp running on this machine and I monitored only one of them (like w3wp.exe/#5) which I knew was the one I was interested in. I monitored for about 3 hours and I know that during these 3 hours the process didn't recycle. What could explain this?
Thanks
