i got this message on a GT: 

WARNING: Process showcase (16519) killed due to bad page read (errno:5)

i've never seen this before.  could it in any way be the fault of the
process?  (i doubt it.)  does it mean my disk is going south?  (i hope not.)
is it a kernel/VM bug?  (irix?  no way.  must be a system V vestige.)

is there anything i can do to capture the circumstances of the error for 
the kernel gurus at sgi?

This one is easy:  you are running a binary which is NFS mounted.  If
you use the "nointr" option on your NFS mount, the problem goes away.
Maybe some NFS guru can give you a good low-level explanation.  I
think it has to do with signals interrupting the NFS calls.

We have seen this quite a lot on diskless PIs, usually the process is cron,
why? we haven't figured it out...
