Going beyond what I wrote at http://stackoverflow.com/questions/36941450/apache-aurora-cron-jobs-are-not-scheduled a few remarks:
* By default, Aurora only keeps a history of 100 finished tasks. It is therefore not expected that the number of completed crons increases, even if everything works as expected. * Is your example cron job in form that you can share with us? That would allow us to try to reproduce your problem more easily. * The location of your log files depends on how you install Aurora. Have you used the official debian packages or RPMs?

I found after scheduled around 100 times, the cron jobs stuck in "PENDING" state. May i ask what kind of logs i can inspect and what is the possible problem ? I tried to restart the Aurora scheduler several times, every time after restarting, the cron jobs starts scheduled but when they hit around 100 time, all cron jobs stops. The BTW, Job executable is a very simple program which just write some number to a file, so i don't think it is a resource problem since i have 40 GB memory/40 CPUs in the slave machine pool Thank you a lot ! -- Regards, Zi-Liang Mail:[email protected]<mailto:mail%[email protected]>
