Description
We're seeing an issue where one server in the ensemble has a steady growing number of QuorumCnxManager$SendWorker threads up to a point where the OS runs out of native threads, and at the same time we see a lot of exceptions in the logs. This is on 3.2.2 and our config looks like:
tickTime=3000 dataDir=/somewhere_thats_not_tmp clientPort=2181 initLimit=10 syncLimit=5 server.0=sv4borg9:2888:3888 server.1=sv4borg10:2888:3888 server.2=sv4borg11:2888:3888 server.3=sv4borg12:2888:3888 server.4=sv4borg13:2888:3888
The issue is on the first server. I'm going to attach threads dumps and logs in moment.
