Hi all, I ran into this problem with these steps: 1: Start master and slave successfully. 2: Stop slave by pressing Ctrl+C. 3: After stopping slave, restart slave within 75s, it prompts this error: Slave asked to shut down by master because 'health check timed out'.
After reading the code and searching on the internet, I knew that after slave being observed disconnected, master continues to send PingSlaveMessage for MAX_SLAVE_PING_TIMEOUTS times, during each time waiting for pong message from slave for SLAVE_PING_TIMEOUT, so the total waiting time is MAX_SLAVE_PING_TIMEOUTS * SLAVE_PING_TIMEOUT=75s, if slave restarts within 75s master believes this slave failsover and accepts re-register request, otherwise, removes this slave. For my situation, within 75s, slave restarts occasionally success, and sometimes failed with message ' Slave asked to shut down by master because 'health check timed out'. I found the bug report MESOS-2679 also discussing this problem, but I think it didn't explain what master checks and what factors may causes health check timed out, could anybody be kind to give more explaination? So we can get away from 'health check timed out'. Thanks very much and best regards!
