Overview
VERIFY_SUSPECT is a protocol that checks a suspected member.
Suspect Verification
!!!Configuration Sample
{{{
<VERIFY_SUSPECT timeout="1500"/>
}}}
!!!Periodic Scans
VERIFY_SUSPECT starts an internal thread ("VERIFY_SUSPECT.TimerThread") when a suspect is added to the suspect table. The thread continually iterates over the entries and removes entries whose time have elapsed. For each removed entry, a SUSPECT event is passed up the stack (because elapsed time means verification of member's liveness failed). Computes the shortest time to wait (min of all timeouts) and waits(time) ms. Will be woken up when entry is removed (in case of successful verification of that member's liveness). Terminates when no entry remains in the table.
