Is it random? Do they have anything in common? If you wait do they eventually execute?
Query in queue means that an execution task has been placed in Redis but has not been picked up by a worker to be executed. This can happen if you have lots of queries running simultaneously without enough workers to handle the load.
You can see the status of your queues from with Redash by viewing the system status.
Also, I strongly encourage you to upgrade to V10.1 which we just release. The v8 codebase you run today is more than three years old and we don’t support it any longer.
There’s not a query per se. You can check the system status page to show all the queues, how many jobs are waiting, how many workers there are etc. Just click your user avatar and then System Information.
What does this mean? Does it mean that a query can execute successfully? If this is the case, do you see your workers behaving as expected in the System Information panel?
It will be easiest to help you if you can provide information about the nature of the errors. 403’s are authentication errors. Where do you see them? In the network inspector? Which URLs return 403’s?
