dynamic linking problems

Set up:
Sun3/50, 4Mb, Sun OS 4.0.3 + Multicasting IP + VMTP
The problem:
Dynamically linked programs fail to execute, returning either:
Segmentation violation
crt0: /usr/lib/ld.so mapping failure
ld.so: Undefined symbol _unbound
(the above errors were produced by ps -xae)
Details:
I'm testing a few applications that use VMTP. When these applications
are running, dynamically linked executables often return one of the
above error messages. When the VMTP applications exit or are
suspended, dynamically linked executables run normally. There does
seem to be a correlation between the amount of VMTP communication
occuring, and the likelyhood that the dynamically linked executable
will die with one of the above errors.
Questions:
1) What conditions would cause dynamic linking to fail?
2) How can I better isolate the problem?
Thanks
Brian
