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 slave stopped, 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 continuously 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 failed with message 'Slave asked to shut down by master because 'health check timed out'. I also found the bug report MESOS-2679 discussing this problem, but I think it didn't explain what master checks and what kinds of reasons may cause health check timed out, could anybody be kind to give more explaination? So I can restart slave successfully all the time. Thanks very much and best regards!
