Hi Mark,

Sounds good.

As soon as it takes over from zeus, unless you have designs of running
zeus and omega in parallel for awhile.  In that case, I would appreciate
you reporting stats from omega which is presumably at LDM-6.0.10 and
stopping the stats reporing from zeus.

No worries.  The real time stats makes it possible for us to easily see
this sort of thing.

The problem is most likely that omega does not have the 'compress' utility
installed.  The McIDAS ADDE server module mcserv tries to run compress
from the /bin, then /usr/ucb, and then /usr/bin directories.  If all
of those locations fail, the transfer will fail.

I am concerned about the core dump messages, but I won't worry about these
until you install compress on omega.  If omega is a Linux box, the standard
location for compress would be /usr/bin.  If it is an x86 box, compress
should be found in /bin, and so on.
