hi
i have a system that has no active users at this point of time. the memory used by the dbw process is very high leading to a lot of swapping when any process starts.
here are the spces
version:9.2.0.4
os:Linux 2.4.9-e.24smp
o/p from top:
1:44pm up 29 days, 23:55, 4 users, load average: 1.73, 1.68, 1.35
