             Summary: The timeout of VERIFY_SUSPECT protocol is not guaranteed
                 Key: JGRP-1429
                 URL: https://issues.jboss.org/browse/JGRP-1429
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 3.0.5
            Reporter: Benoit Leblanc
            Assignee: Bela Ban

The verification of a suspected member can take more than timeout. It depend of being followed closely by other suspected members or not.

Let's timeout = 2000ms.

- At T: Member A is suspected (by Failure Detection protocol).
- At T +  1500ms:  Member B is suspected too.

Member A is declared as definitively dead 3500ms later. The "worst case" occurs when a continuous flow of suspected members arrive with an interval between 0 and 2000ms (timeout). Suspected members are never removed from view.
