Java overrides some of the standard C library calls in a slightly
incompatible fashion. This usually doesn't cause a problem, but sometimes
it does.

Can you find out what MLDBM is trying to do when it gets this error
message?  You could either use a tool similar to strace or truss, or look
in the MLDBM source and look around for this error string.  Maybe there is
something happening that just doesn't work with the overridden calls.

I haven't tried this myself, yet - I have a 712/60 with HP-UX 11.00, but
it's been in storage because of a lack of space (and a spare monitor)...
