Sorry for the late answer - I was unable to reproduce the problem at home and even at work it takes some time before it's obviously visible. Now, after ~25hours, I see it again. Fstat and lsof in single-user really only show small number of files (these of fstat, sh and init) yet kern.openfiles was 729. Output of "sysctl kern.malloc | grep 'file desc'" is "file desc 47 12K 29K 6801 256". I've got all sysctl -a saved if anything from it might give another clue. I forced panic from the DDB so I've got coredump if needed. I think it's mozilla (and libkse) what's causing this. It seems to happen after many pages are loaded (I leave the computer running when I leave on https page which reloads every minute). At home I tried with self refreshing local page without SSL and the problem didn't occur. -- Michal Mertl
