Excessive disk activities...

[achana saysit com]

Hi !

H/W  : Adaptec SCSI Seagate disks with swap = 2x512k memory .
S/W   : RedHat7.1 / Oracle 9i Standard / j2sdk1.4.0 .

Once or twice a day, I notice excessive disk activities, really
thrashing the disks, as if memory is being dumped into swap.
It happens at night too, when there is practically no work acitivities.
There is a comstant , very low level of disk activity clicking away,
regardless of whether there is any work going on .

Has anyone noticed that and is it a problem ?

Kind Regards,
Arthur Chan
