I would appreciate any expert insight into a problem that is causing me considerable grief. Please cc to me directly. Thank you very much. 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. -- Art Hays avhays@nih.gov or art@lsr.nei.nih.gov Bldg 49 Rm 2A50 (301) 496-7143 (voice) Nat.
