I also have this problem. Unknown circumstances provoke it. Kernel
2.4.9 to 2.4.13. When it occurs I lose about 30MB a day.
Dual 500MHz i686, 4 scsi disks (adaptec) under raid5 and raid0
with 2 intelpro's and 1 IDE disk (and xfs and lvm).
Right now I'm on 2.4.9 and it's NOT happening. Doing nothing different
to any other day.

Same.

Only thing in common with me is nfs. Running X 4.1. glibc 2.1.

Could be.

My mobo is whatever came from dell, and you also are running 2xP3. My
ram is also ECC but there's only 128MB of it.

I have 2 network cards, both EEPRO.

Yep, I have internal adaptec too. Aic7xxx running ultra 160 at 20MHz
on terminated cable.
Adaptec AIC7xxx driver version: 6.2.1

Umm .. I think I run ati rage, external card, though there is one on
the mobo.

I have it all compiled OUT. Including iptables, which I don't use.

I am using xfs on top of lvm on top of raid5.

Mine isn't. Normal setup.

Looks from this as though it might be raid5 or 0 + adaptec scsi + SMP.
