Problem conclusion
RESOLUTION SUMMARY: THIS MULTIPLE TOKEN NODES ISSUE IS A TIMING ISSUE. THE FIX INCLUDES: 1. HAVE A LOCK WHEN HEART BEAT THREAD UPDATES DATABASE TO CLEAN TOKEN NODE AND TAKES TOKEN FOR CURRENT NODE, SO WE DON'T HAVE TWO NODES TAKING THE TOKEN AT THE SAME TIME. 2. UPDATE TO MAKE SURE NO ACTIVE NODE HAS THE TOKEN BEFORE TAKING THE TOKEN FOR CURRENT NODE. THESE CHANGE ENSURES ONLY ONE NODE TAKES TOKEN WHEN A NODE GOES DOWN. DELIVERED IN: 5020500_1
