My mistake -- it was paging for at least 30 minutes before I reset it. I discovered that just now because my clock was behind by 30 minutes! Apparently, all the paging activity significantly delayed the system clock, and because I was using NTP, the OS wrote the delayed values to the hardware clock. Something is seriously wrong if excessive paging can mess with the system clock. Please can you attach a dmesg after boot and info on how much ram you have Created attachment 92662 [details]
dmesg log after boot
My dmesg log after rebooting after the described failure.
I have 512 Mb RAM.
It happened again today, and here is some more information. I had several memory soaking apps running. About 90% of my swap space was used and 80% of my RAM was in use. My system had been running for only 2.5 hours since the last reboot. The major VM users: Opera: 314 MB Open Office: 262 MB Nautilus: 106 MB Evolution: 194 MB GIMP: 70 MB (total of these: 946 MB) Except for Evolution, all of the other windows were open in the same workspace. I was using GIMP. Switching between applications caused some heavy paging and mild slugishness. At some point, I saved and then quit GIMP, and then the swapping hell began. 15 minutes later, the last of the GIMP windows finally disappeared and my system was usable again. While swapping furiously, the mouse cursor moved with no hesitation. I am running gkrellm to show system status, and it froze for the entire 15 minutes. a patch for this problem was recently added to the Red Hat Linux 9 kernel, I expect it will be released with one of the next security erratas Actually, now I think this is a Gimp bug.
