Hi Kesava, It's just a guess, I assume that the cron entry in question was supposed to run on "dynamic" backend instance. If that's the case, the cron execution can be a single point of failure, because the cron never retries.
I'd suggest directing all the cron execution to FE, and for the task you want to run on backend instances, put a task on a queue associated to the backend instance. That way, you can mitigate the risk that the cron execution ends up with an error. Additionally, you can make the initial cron call redundant in a safe way if you use named tasks. hope it helps! -- Takashi On Thu, Jun 21, 2012 at 7:01 PM, Kesava Neeli <[email protected]> wrote: > Hi, > > We have many cron jobs that run as part of our application.
