I don't think it's a cisco problem.  In the above example I did a
"clogin nexus5000-1" and then typed in "show version build-info all"
at the prompt.  Got the error msg & new prompt - no disconnect.

& I just noticed that doing an "export NOPIPE=YES" before the
"rancid-run -r nexus5000-1" doesn't have the 'broken pipe' msg.  I
don't get a new config since it complains about missing commands, but
if it was cisco ending the ssh session wouldn't I still be getting the
broken pipe error message?

I must be especially slow today - what am I looking for?  Looking in
nexus5000-2.raw shows some extra "^M"s, but it's still the same as my
earlier example - no output:

  Core Plugin, Ethernet Plugin^Mnexus5000-2# show license^M^M
^Mnexus5000-2# show license usage^M^M
Feature                      Ins  Lic   Status Expiry Date Comments^M

and the last few lines in my terminal window are:

HIT COMMAND:nexus5000-2# show running-config
    In WriteTerm: nexus5000-2# show running-config
nexus5000-2: found exit
nexus5000-2: missed cmd(s): show license
nexus5000-2: missed cmd(s): show license

Thank you - I really appreciate the help.
