Hi, @Frank Thanks for your information > I see messages 'Telling agent (...) to kill task (...)'. Why does this happen? This should because your framework send a `KillTaskMessage` or `scheduler::Call::KILL` request to the Mesos Master, then the Mesos is going to kill your task.
>Is this the exact text to search for or is this the name of the protobuf message? Are these logged on a higher log level? it exists in the log of the agents. It looks like ``` I1004 23:19:36.175673 45405 slave.cpp:1539] Got assigned task '1' for framework e7287433-36f9-48dd-8633-8a6ac7083a43-0000 I1004 23:19:36.176206 45405 slave.cpp:1696] Launching task '1' for framework e7287433-36f9-48dd-8633-8a6ac7083a43-0000 ``` Usually, you could grep your task id in the agent log to see how the task failed.
