Good question, but NO.
No exports or lock daemons running.
Could it be any activity that uses kernel space? Network, local ATA
disc or X11? Machine is not running NFS. Do not know what triggered it.
This is a 32-bit machine running an MTA (exim4-daemon-heavy) with
scanners. Often the user space Microsoft virus scanner (clamav-daemon)
refuses connections. A segfault on pointer deref is always nicer than
a kernel panic.
It is a small _one_ way 32-bit machine: -

Also running MTA on 2.6.26-2-amd64 on amd64 with 4 GiB physical. Less
probs with that machine and it does a lot of email. Running linux-image
from the same linux-source. The 32-bit powerpc is just my home email.
I.e. linux-image-2.6.26-2-amd64_2.6.26-19 is running okay with that
workload. This has NFS homes for Maildir delivery to 500 users on
Solaris/ZFS. It is headless and has console redirected to serial in
BIOS. (Vintage Sun X2100 without M2 still in service running upgraded
original Debian i386.)
