Hi All,
I had a VM problem for the last couple of months and I thought it due to my
hardware, which I replaced this week and still get this problem. I'll explain:
I'm running here KDE 2.2.1 with server Konsole sessions running, and using
mondo-archive program to backup my machine. After the backup finishes part of
the backup - the VM panic randomly - sometimes it's the bzip2 process which
the mondo uses, sometimes the afio which the mondo uses, sometimes its just
the kswapd daemon, sometimes wineX which I'm testing - so as you can see from
the pattern - it's not a program or a module that does it yet it happends to
me on both machines
I have checked the RAM of the machines twice - with memtest86 2.8 for 24
hours - no errors.
I checked the machines - one AMD 800Mhz thunderbird + Asus A7V board, and
once Pentium 4 1.5Ghz with Intel board (i845 chipset) - so it's not the
processors or the boards.
I checked the hard drive (40GB EIDE IBM 7200RPM with a fan) - no sectors or
any disk problems. Sound card is SBLive - no problems there either...
Here is the output from /var/log/messages:

So if my RAM is ok, disk ok, processor ok, plenty of air cooling (6 fans!),
graphics & sounds card seems working ok (SB Live & Geforce 2 Ti - with &
without the binary only drivers, and I also tried Matrox G400 with the open
source drivers) then what could cause this?
Thanks,
Hetz
PS: It seems that there is still some problem with the vger server - I get
the first email to subscribe but when I reply with the auth - it doesn't give
me anything and I think my ISP doesn't have any issues with ECN.
