Resolution: Fixed
> Attempts to send messages to alert listeners delays network partition
> detection

> Key: GEODE-7031
> URL: https://issues.apache.org/jira/browse/GEODE-7031
> Project: Geode
> Issue Type: Improvement
> Components: membership
> Reporter: Bruce Schuchardt
> Assignee: Bruce Schuchardt
> Priority: Major
> Time Spent: 2h 50m
> Remaining Estimate: 0h
>
> In a number of recent regression test runs in AWS we have seen network
> partition detection tests fail to detect the partition in a reasonable amount
> of time. Logs show membership services attempting to send alerts to other
> processes that are no longer reachable. Each attempt takes 6 * the
> member-timeout setting - that's 30 seconds for each attempt. It would be
> nice to have a different connection-formation timeout for something like this
> since alert notification is built into the logging system that membership
> services have to use. Since the alert system is also dependent on membership
> services functioning properly this creates a circular dependency that has
> historically caused hangs and delays such as the one described here.
