kjournald using up majority cpu%.
We run several RH7.2/7.3 servers & recently 2 of them, although still working fine, have started to show kjournald as generally using over 50% cpu% on 'top' - virtually continuously. Free cpu% generally less than 25% now! Both machines are also using software RAID5 EIDE ....... otherwise are standard server installs. Any info on what kjournald is & why it should have recently

On very different journalling activity on 2 servers.
Hello Folks, We have 2 (identical hardware) busy public 2U rack servers, both have several hundred users & peak email (for example) deliveries at 300/5min during the daytime. Both servers run RAID1 over 2 EIDE disk drives. One server is fine - it never has problems - it is running RH7.3 and CPU loads are normal. The other server has constant disk activity & kjournald at CPU load of

sync slowness. ext3 on VIA vt82c686b
When I copy a file(13Megs) from /home/ to /tmp/, sync takes almost 2 minutes. When I copy the same file to /usr/local/, sync returns almost right away. Both filesystems are ext3 and are on the same harddrive. When sync is running, the harddrive light stays on but I don't hear it doing anything. dmesg doesn't show any errors either. Below is the `time` output for each command. If you
