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

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

We are you using ldap too and the settings are bellow. The network is up as I''m restarting shorewall whilst the machine is running. Any suggestions? Is there no way to

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
