My server is a Fedora 7 box that shares a Canon iP4200 printer and a few disk drives to my lan. It also runs the Folding At Home Client. It seems that I randomly get issues where a process called "usb" uses everything in the machine (goes to 99% CPU), killing my Folding@Home performance on this machine. It is usually not discovered until days later when I SSH in. TOP shows that the process is being run by the "lp" user, which I would assume pins it down to something to do with CUPS. A reboot usually cures the problem. I do not know how to reproduce this problem, it seems to happen randomly. Finally, if there is any way to fix this completely from the command line, that'd be nice because I do not have a keyboard, mouse, or monitor plugged into this machine right now. If that cannot be done, thats fine, but... If anyone has any ideas, I'm all ears ;) Billy3 -------------------- In the event I fail to reply within twenty-four hours, feel free to send me a PM.

/var/log/messages would be the first place to look.
See if something in there gives some info to go on. -------------------- |

Alright... I think I have it figured out. Whenever someone sends a job to the printer and the printer is off, it happens. Maybe CUPS constantly trying to resend the job. It appears the Auto-Turn-On feature of the windows driver is unavailable in the linux one. I am simply going to leave the printer on all the time to end the problem.
Thank you all, Billy3 -------------------- In the event I fail to reply within twenty-four hours, feel free to send me a PM.
