Help understanding error message?

[Steve Wampler <swampler@noao.edu>]

System(s): 11 identical 2-cpu Althon boxes
            RH 8.0, kernel 2.4.18-24.8.0/smp
            nfs-utils-1.0.1-2

We're trying to track down a problem and need help
understanding what an error message means (and what
might be causing it...)

Background:  We have 11 identical Linux RH 8.0 boxes
(dual-cpu Athlons).  One of them exports a filesystem
via NFS to the other 10 (and to 5 other [different]
Linux boxes as well).

Running a specific program on each of the 10 machines
works sometimes and not others.  The machines on which
it fails changes, but once it fails it continues to
do so until we remount (unmount+mount, not with
"-o remount") the NFS directory.  After the remount
the program functions properly.

Here is the error message (split to fit):

jboc-03:18> runwip
    ../../../Bin/Linux/DHS/vsmWip:
    error while loading shared libraries:
    /opt/solis/devel/release/Lib/Linux/DHS/libprocess.so:
    unexpected PLTreloc type 0xec

Both the program (vsmWip) and the offending shared
library libprocess.so are located on the NFS-mounted FS.

I couldn't find a reference to 'unexpected PLTreloc'
in mailing list archive search.

[Also, I've just discovered that ldd gives a segmentation
fault:

   ->ldd vsmWip
   /usr/bin/ldd: line 1: 15403 Segmentation fault
       LD_TRACE_LOADED_OBJECTS=1 LD_WARN= LD_BIND_NOW=
       LD_LIBRARY_VERSION=$verify_out LD_VERBOSE= "$file"
   ->

if LD_LIBRARY_PATH is set to include the library
directory on the NFS mount.  (Without that directory,
ldd [correctly] simply identifies the shared libraries
as missing.  ldd works properly in either case after
a remount of the NFS mount.]


*ANY* help is appreciated.  Thanks in advance!

This is fairly new behavior, though we're now using the
system more heavily than previously.
