An update: This particular behavior I observed no longer occurs with 2.4.9-13smp, the latest update supplied by Redhat. Thanks for all the very helpful info I received. > 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. -- Art Hays avhays@nih.gov or art@lsr.nei.nih.gov Bldg 49 Rm 2A50 (301) 496-7143 (voice) Nat.
