IceStorm hangs
I've got a simple publish/subscribe example running. The publisher publishes some info every second, the subscriber reads the info successfully. The qos is oneway. The subscriber is on a windows pc and the publisher and IceStorm are on a linux box.
If I quit the subscriber, IceStorm seems to realize the subscriber is gone, but then it just hangs. This also hangs the publisher. Eventually it times out the publisher connection.
I saw a forum thread that suggested setting the Ice.Override.Timeout which I've tried. That works, but is there a way to have IceStorm just remove the subscriber without having to set a timeout? Any idea why IceStorm hangs when the timeout isn't set?
This is the network trace for a session with no timeout. 10.1.21.52:4644 is
the subscriber. 10.1.5.30:51666 is the publisher.

closes connection to publisher since it's been hung by the subscriber
going away.
