Are you aware of any side-effects of increasing the messaging.clientReconnectWindow? Do you suggest tuning it to as low a value as possible?

There really isn't . There is potentially a way to abuse this in a DDOS scenario, but the reality is that there are many other equally good ways to consume server resources even in any given configuration (not specific to SmartClient/SmartGWT).

This was just tuned too aggressively and we've now set this 1 minute by default (in the latest stable builds of all releases). The client is responsible for reconnecting and the right thing to do is continue using the previously known working channel until the connection is re-established.
