Heroku Scheduler Memory Quota Exceeded Constantly (Java Play)

We are running a Java Play project on Heroku and have been getting endless Error R14 (Memory Quota Exceeded) on the Heroku/scheduler dyno all day.

heroku/scheduler.3831: Process running mem=1058M(103.1%)

heroku/scheduler.3831: Error R14 (Memory quota exceeded)

We currently have 5 daily jobs scheduled, but they all occur after business hours. For some reason though the Heroku/scheduler dyno is hitting memory quota caps all day, despite no jobs actually running.

The web dynos are working without an issue. Has anyone encountered this issue with Heroku Scheduler?

You could try bumping the dyno size for your scheduler job (ex: Standard-1X -> Standard-2X)

I'd recommend lowering the max heap size on the scheduler process. Play is somewhat notorious for using lots of native (off-heap) memory (mostly because due to Netty I think). If you lower the heap size, it should allow more room for the native memory.

You can set the max heap size with an option like -Xmx300m on the java command that the scheduler runs.
