Environment
Novell NetWare 6.5 Support Pack 6
Situation
High utilization was being caused on the Netware server due to
memory constantly being mapped between the pools and never settling
down. This was due to nss constantly mapping the memory for its
cache. The garbage collection interval was still set at the default
of 5 minutes. The problem appears to be when the machine has less
physical ram than the FCMS line. The OS is therefore always trying
to move memory down to the L=P pool. One of the symptoms would be
that the cache buffers would rapidly disappear and then reappear as
the the vm pool mapped the memory back down to the L=P pool.
Resolution
Put a hard limit on the amount of memory nss uses.
