rfs_read errors

[sae!ken at uunet.uu.net]

Ever since we upgraded our Sun 3's and Sparcstations to SunOS4.1.1, we've
started getting occasional 'rfs_read: attempt to read from non-file'
errors on the consoles of our Suns.  We don't use RFS anywhere, but we do
use NFS.  Our SS1 ground to a halt the other day while spewing out these
messages non-stop.  A 'ps aux' showed the nfsd processes to using more
than 70% of the CPU.  This persisted even after several reboots but
stopped later in the evening for no apparent reason.

Does anyone out there have any idea what is going on?
