I have been troubleshooting failed jobs and have narrowed it down to the middleware I put on both jobs (WithoutOverlapping). I use the same key in both jobs, and each job is permitted the following:

• 5 tries
• 2 max exceptions

The jobs are (by design) not working with the same files on the server and so are queued simultaneously. I have seen that in the first try for each, one of them is getting failed(). The error message is: Illuminate\Queue\MaxAttemptsExceededException with a description that has the job name and then has been attempted too many times or run too long. The job may have previously timed out.. It's been confusing because the failed jobs are clearly getting failed in the middle of the job itself, so it's not due to any of the items in the error description.

It appears that the overlap middleware is causing this - does this seem right? I was expecting it should not fail at all and instead be preventing the starting of the job in the first place.

Does the WithoutOverlapping prevent the job from starting or fail/re-queue it when the overlapping job starts?

EDIT: I changed the job overlap keys to different strings and the same job is seen as failing if the job is queued in quick succession. The second job instance starts before the first job instance has ended, and the second job instance is seen as failing.

EDIT 2: I just found missing parentheses around the WithoutOverlapping class.

EDIT 3: with parentheses, still no difference. Example, I have logger() outputting these:
