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. Last night I noticed a syslog saying "mb_map full" around the >time of the freeze, did a check, and found a load of those corresponding >roughly with previous freeze-ups. >Question: Would it be fixed by increasing MAX_KMAP in >/usr/src/sys/vm/vm_map.h ?
