.I had this problem, too and it turns out to be a hardware problem (too agressive timing values in BIOS) on ASUS-Trition-PCI board. This is under NetBSD-1.0, but if you cannot solve the problem by chnaging kernel values, have a look at this. In hanse-ml.freebsd.hackers you write: >We are currently having a major problem. >Our news server is a heavily used machine, is a pentium, has 128M RAM and >128M swap space, and is usually up to 80% swapbound. >The problem is that the system seems to temporarily freeze for minutes at >a time.
