问题
In my code i run a cron job which is run for every five seconds, and I've been getting the same WARNING ever since.
this is the api that i used:
sched.add_cron_job(test_3, second="*/5")
And I get a warning:
WARNING:apscheduler.scheduler:Execution of job "test_3 (trigger: cron[second='*/5'], next run at: 2013-11-28 15:56:30)" skipped: maximum number of running instances reached (1)
I tried giving time gap of 2 minutes it doesn't solve the issue..... Help me in overcoming this issue..
回答1:
I used the proc.terminate() to stop the execution of my method. So that the instance of the 1st thread is terminated before a new thread could start again.
Also provide a timing mechanism to complete your process well within the scheduled time say within a minute, hour or day etc. In my application i used *sleep(in_seconds)* for providing the timing mechanism.

I had a similar problem, and it turned out it was just your job 'test_3' lasting too long, more then 5 secs (or 2 minutes as you tried). APScheduler is trying to re-execute you job, but the previous one is still running.
