hey all,
i was trying to pull down a db from a remote server via pull replication to 
my laptop. now, it's windows, and therefore suspect, but this may be
something else. when i attempt pull replication initiated from windows 0.91 
laptop to ubuntu 0.10 server, it crashes with this stack:

when i decided to try to push from the ubuntu server to the laptop (ports 5984 was opened on both attempts), everything went swimmingly. this last part makes me think that may be this is a firewall issue of some sort. for pull replication, do the dbs attempt to talk over any port other than 5984 
(or whatever is configured locally)?

thanks,
alex.
I'm guessing this is a bug in the Windows startup script. It needs to execute ibrowse:start(), but it hasn't. The firewall doesn't appear to play a role at all. The reason push replication works is that your Ubuntu machine is making the HTTP requests, so ibrowse on the Windows machine is not involved. And
do the dbs attempt to talk over any port other than 5984 (or whatever is configured locally)? 

Nope, they don't.  Best, Adam
