I have 4 times got the smae issue, where all tasks get stuck in the same parallel gateway. Only solutionhas been to delete the database, deploy a new db and deploy the same Process definition.
Running 7.18.

Note: All stuck taks has 3 retries.
I see that you have ASync After on your parallel gateway, but can you try “ASync Before” on your Resize tasks?
I think the Parallel Split is working correctly, since you’ve got 268 tokens, but something’s not happy with your first External Task, so it rolls back to the last transaction point.
But anyway, it’s worth a try!
I didn’t suggest that there is… just noted that they had done it.
I still think there’s something going wrong with the External task which is rolling back to the last Async.
Yeah bro @GotnOGuts … I also believe it’s something in the service task code.

I see no need for Asynchronous continuation on the gateway bro… I would remove that and just put an async in tasks.
