So I turned on "options INVARIANTS" and "options INVARIANT_SUPPORT", rebuilt my kernel, rebooted, and now, tah-dah, it doesn't crash (at least, not yet). I did get an odd "xl0: watchdog timeout" or two, but the system is still running after 8 hours of heavy NFS traffic (would have killed it in minutes before). Interesting, ehh? Ian, I didn't apply the patch to mbuf.h yet (added the options from memory and didn't remember the patch until I went back and looked at your mail just now). If it panics, I'll put the patch in and try again. So what exactly does INVARIANTS do? According to LINT, it enables extra sanity checking of internal structures (making the system slower). Seems to be a lot of people reporting crashing problems on 4.5, even on hardware that was previously stable. Could be we have a real problem here? -jan- -- Jan L.
