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 ? If not, then how can I eliminate this
problem?
Apparently, nothing is lost during the freeze-ups, and as a matter of
fact, everything just picks up right where it left off. I have ruled out
"swap_pager: out of space", as we only saw that again two days ago [time
for yet another memory upgrade].
Jim
