• Wow, we have been fighting this same issue and it is really driving us nuts. Is there any reference info on the hotfix you can provide so we can get it? We have the same issue where it appears that sql believes there is a low memory situation and begins dropping the buffer cache with a corresponding drop in PLE. All the memory is released to free memory and not used. The buffer will then try to fill back up then drop to zero again. This will eventually clear itself or if I run DBCC FREESYSTEMCACHE ('ALL') it will return to normal right away.

    Again, any help would be appreciated.

    Thanks,

    Erik
