The kjournald process starts sometimes on my Debian web server.
When I run top, the kjournald process eats up 100% of the CPU utilization.
After an hour that the process runs, my web server (apache) does not respond anything to requests (my site is down), but I can access SSH via putty (very slow though).
When I show uptime, I get this:
debian:/home/jonathan# uptime 08:11:56 up 15:14, 1 user, load average: 101.06, 50.67, 30.41
This happens like once a week or so. When this happens, I must reboot to take my server up to its normal state. When I input reboot command, the server just dont reboot and I don't know why. I must hard reboot with the front button, like in the "Windows 95" days!
