I have also experienced this. A SIGHUP or a SIGTERM will gracefully shut it down. So look for anything in your system throwing those. Pretty much any other signal will kill it outright.

Hi All,

After flume agent is started at 1:10 and it shut itself down at 2:08. No errors, but graceful shutdown. This situation has happened several times.
My question is what will possibly gracefully shut down flume? Or which side of environment should I pay attention to to trace the error or find the root cause? 

Thanks
