Problem: kswapd, kreclaimd, kupdated push load average high during simple
tar. Response of system drops such that even keystroke echos are
noticeably delayed.
Specifics:
Machine- 4 processor 700Mhz Dell with 4G Ram and 6G swap space running
stock Redhat 7.2 distribution. All disks are SCSI using ext2.
Command- from a remote machine this command is executed to the Linux
machine "tar cBf - . | rsh linux "(tar xBpf -)".
Manifestion of problem- As this command continues on a freshly booted
Linux machine the free memory reported by 'top' slowly goes to a low
number. When it bottoms out, the processes 'kswapd', 'kreclaimd', and
'kupdated' begin to run pushing the load average above 4 at times.
Responsiveness of machine drops dramatically with even keystroke echos
delayed for seconds.
I apologize if this is well known. If there is a simple solution I would
appreciate even a terse pointer to it. Thanks.
