             Summary: potential hang
                 Key: GEODE-7591
                 URL: https://issues.apache.org/jira/browse/GEODE-7591
             Project: Geode
          Issue Type: Improvement
          Components: membership
            Reporter: Bruce J Schuchardt


This method in ClusterDistributionManager waits for a new membership view to be installed, but if the cache is being closed while waiting the method could hang because it only checks for cache closure if the object it's waiting on is notified.  We should change the wait() to have a timeout so that the `stopper` is polled periodically
{code:java}
void waitForViewInstallation(long id) throws InterruptedException {
  if (id <= membershipViewIdAcknowledged) {
    return;
  }
  synchronized (membershipViewIdGuard) {
    while (membershipViewIdAcknowledged < id && !stopper.isCancelInProgress()) {
      if (logger.isDebugEnabled()) {
        logger.debug("waiting for view {}.  Current DM view processed by all listeners is {}", id,
            membershipViewIdAcknowledged);
      }
      membershipViewIdGuard.wait();
    }
  }
}
 {code}
