> JGRP-1401 deals with crashes of the site master *within* the current site, and developed FORWARD_TO_COORD to deal with those temporary losses (a new coord will take over), to prevent message loss.
> *This* JIRA is about preventing message loss caused by the site master of a *remote site* crashing. The general idea is to store-and-forward a message for a certain time and/or a certain number of attempts to forward.
> The most frequent use case is probably that the site master of a remote site left (or crashed) and the new site master hasn't yet opened the bridge, so the message would be lost. Store-and-forward should help here.
> If we still cannot forward the message for a (configurable) time and/or number of tries, we'll send a SITE_UNREACHABLE message back to the original sender of the message, which will then have to deal with it.
