Hi Robert Cullen, 1. You may solve the problem by increasing the timeout by define `heartbeat.timeout` [1], however I do not recommend this way because it will hide the real problem. 2. Please find out the gc log and log of timeout-taskmanager(10.42.0.49:6122 -e26293), check 1. is there memory leak? 2. is there full gc near the moment `2021-05-27 10:24:21`. Maybe you could share the log here.
