NFS server errors; LOTS of DUMPs

(Ah, the MIDRANGE-L floodgates have opened once again!)

I've got a V4R4 box on which we are using the NFS servers.  For reasons
unknown to me, within the past week we have been getting thousands of dumps -
a combination of QPDSPJOB (Display Job) and QPSRVDMP (Service Dump) reports -
over the course of a day.  These are being generated by the QNFSNFSD job.

I have been unable to determine a pattern for these dumps.  The cycle
*appears* to be:
CPF2204: User profile  not found.
CPF9999: Function check. CPF2204 unmonitored by QODCRT ...
CPF9076: Internal system error processing documents or folders.
CPF3698: Dump output directed to spooled file 4677.
CPF0963: Complete thread information not available.
CPD2454: The requested information cannot be dumped.
  *** Cause . . . . . :   Message CPF9076 requested field format 6
       to be dumped.  It contains a pointer that is not valid so
       the requested information cannot be dumped.
>>> Message CPD2454 is repeated several times, each with a different field
format number reference.
CPF9999: Function check. CPF9076 unmonitored by QODCRT ...
