Not an erlanger but can vi, can you tell me what to put there?  Currently it is:
            exit(normal)

Sorry, but I mean the entire couchdb process, not just the replication process
I initiate the request from the remote machine (.194)  it fails out
after a while with, the error, then

jlh@mars:~$ ps ax|grep couch
28145 pts/2    S+     0:00 tail -f /usr/local/var/log/couchdb/couch.log
28375 pts/3    S+     0:00 grep couch
jlh@mars:~$ sudo /usr/local/etc/init.d/couchdb status

jlh@mars:~$

All couch related processes are now -- gone. on .194

couchdb on the remote machine (.52) is just humming along fine.

Let me know what you need and I'll do my best.  Sorry for the long
pause between the first report and now.  I was dashing out of the
house to work and wanted to get the initial report out.

Regards,

Jeff
