PingOhDearJob keeps failing

[phadaphunk]

Most of our OhDear pings fail with the following exception :

Illuminate\Queue\MaxAttemptsExceededException: Spatie\ScheduleMonitor\Jobs\PingOhDearJob has been attempted too many times or run too long. The job may have previously timed out. in /home/forge/production-worker/vendor/laravel/framework/src/Illuminate/Queue/Worker.php:750

The worker has a 240s timeout and it is a single alert sent to OhDear so it should be pretty quick. Our queue worker is database and it has a 9000 retry_after so it should not get sent back to the queue because the job is taking too long.

Anyone encountered this?
