Thanks David and Paul.
Great help quickly as usual. The ulimit was set to 256.

Sounds like a Solaris system limit - what is the output of "ulimit -a" in
csh?
Since the multiplexor opens each of the slaves and maintains several file
descriptors (I assume stdin/stdout/stderr as a minimum) for each slave,
plus
sockets and library files, I would guess that the default limit of 256
descriptors is being hit. This can be changed to 1024 under csh using
"limit
descriptors 1024", but to go above this you have to reconfigure the kernel.
See "man limit" for details of the names and sh/ksh equivs.
Best Wishes,
Paul.
