Hello, If I create a lot of vn-backed filesystems ... say ... 30 of them, and then do heavy i/o inside one or more of them, I can reliably lock up a FreeBSD 4.x system. I have seen this in every version from 4.5-4.8. Two questions: 1) can anyone confirm this ? Has this been discussed ? 2) I seem to remember that someone mentioned that this problem might not manifest itself if each vn-backed filesystem was inside of its own directory - as opposed to having all of the vn-files and the mount points all inside the same directory. Comments ? Actually, any comments at all relating to large numbers of vn-backed filesystems causing crashes is appreciated. thank.
