I have a couple of Supermicro servers which got the similar kernel panic = with all FreeBSD versions I tried since 6.4. Now I want to investigate into the problem. The servers get into panic with similar workload: file server with a lot = of files and connections. Web server software is nginx. File system is = UFS+GJOURNAL. Outgoing traffic on each server is ~10 MB/s. I think it is not software problem, because when I've installed Linux = with such configuration there were no kernel panics.
