IMHO, just reading this mailing list will give you an overly negative view of FreeBSD's stability. My experiences are that FreeBSD 5.4 using a GENERIC kernel (or something close to it) is quite stable. I'm only aware of one issue - relating to an interaction between mysnc(2) and UFS2 snapshots - and that hasn't affected me so far.. Most of the problems I've seen on this list relate to one or more of: - Experimenting with the ULE scheduler (which is not used by default) - Experimenting with PREEMPTION (which is off by default) - Having machines with 4GB or more of RAM - Running 5-STABLE (the development version) rather than 5.4 - Having filesystems with lots (>>1e6) of inodes - Unusual hardware (eg laptops) My suggestion is that you install your application suite on FreeBSD 5.4 (either native or within VMware) and experiment for a while. Your own applications are by far the best test. If you're happy with FreeBSD, switch over. If you run into problems, let us know. At this stage, I would recommend 5.4 over 4.11. -- Peter Jeremy
