Message-ID: <1282@kaist.UUCP> Date: Mon, 21-Jan-85 12:24:23 EST Article-I.D.: kaist.1282 Posted: Mon Jan 21 12:24:23 1985 Date-Received: Mon, 21-Jan-85 03:45:46 EST Organization: KAIST, Seoul, Republic of Korea Lines: 21 Somewhile ago, our VAX 780 showed a disastrous performance. It couldn't even echo the keystrokes from the terminal not to say of any works. 'uptime' reported 14 users, load average about 4.5. I only had to halt the cpu (^P) followed by a reboot. As far as I can guess, it surely is a thrashing, a rarely occurence. If you have any experience, please send me relevent information. Like the cause you found, the remedy, etc. Here is the disk usage for reference ( any hint? ).
