(I'm resending this message of October 31, 2015 which was
misclassified as spam by seas.upenn.edu <http://seas.upenn.edu/>; I did not get a reply from
postmaster at seas.upenn.edu <mailto:postmaster at seas.upenn.edu> when I enquired as to the reason)

Hello Hackers,

I ran into a strange error after some updates on a remote account
(ofb.net <http://ofb.net/>). Basically, I propagated a new .zprofile to ofb.net <http://ofb.net/> which
changed my PATH to exclude unison, so that it didn't work when I
invoked it locally (complaining that the version was different on the
server, since there is an old version in ofb.net <http://ofb.net/>:/usr/bin/), and then
when I put $HOME/bin back in PATH (on ofb.net <http://ofb.net/>), I got this error.

There may have been other changes which caused the error, but I'm
curious because when I search Google for "unison out of memory", the
only thing that comes up is about when you have huge directories,
which I don't think is the case here:

   $ unison home-config . ssh://ofb.net/ <ssh://ofb.net/>
   Contacting server...
   Connected [//ofb.net//home/frederik <http://ofb.net//home/frederik> -> //thutmose//home/frederik]
   Looking for changes
     Waiting for changes from server
     Reconciling changes

Any ideas?

Thank you,
