[GitHub] [pinot] jadami10 commented on issue #8352: Pinot server stops processing Helix messages when it loses connection to ZK

   @Jackie-Jiang I'm resurfacing this issue as it hit multiple of our clusters this week. There were zookeeper leader elections that were then followed by severe degradation throughout pinot: tons of traffic between zk <> controller and zk <> server, unable to commit segments, high zk latency, and more.
   
   We saw ~.5 million `SessionId does NOT match` messages per hour coming from servers that went away once we restarted the servers
