I’m getting a DRbServerNotFound exception on TupleSpace#take but not
TupleSpace#read. I’m running ruby 1.8.5 on fedora core 6.
Here’s a little snippet:
@http_server.mount_proc(’/delete’) do |req, res|
id = req.path_info.reverse.chop.reverse
@seldom_space.read([‘pending’, nil, id, nil], 2)
@seldom_space.take([‘pending’, nil, id, nil], 2)
res.body = get_status
end
Basically @seldom_space is a TupleSpaceProxy that I’m accessing from
within
a Webrick proc servlet. The read will work as expected and return a
‘pending’ tuple with the specified id. The take is throwing the
following
exception:

Anyone have an idea what’s going on? I’ve been stepping through DRb
with
ruby-debug for hours and I’m not able to wrap my mind around what’s
happening (though I have learned a lot about more about DRb).
