Queries not refreshing; possibly no background processes running?

[jonahgreenthal]

Since I upgraded to Redash 10, my scheduled queries have not been refreshing.

I've tried a ton of troubleshooting steps found by searching this repo's issues and discussions, as well as things I found on other sites, but nothing seems to help.

Here's my /admin/status:

The queues keep growing. I've purged them several times; one was in the tens of thousands before I purged.

Here's /admin/queries/jobs:

/admin/queries/outdated produces an error; I don't know if that's a hint.

Here's my docker-compose.yml. The commented-out lines are from previous troubleshooting attempts:

It's running on an EC2 t2.small instance with a bunch of swap space because I know Redash 10 is memory-hungry. Here's top:

top - 05:16:50 up 9 min,  2 users,  load average: 0.00, 0.33, 0.33
Tasks: 142 total,   1 running, 141 sleeping,   0 stopped,   0 zombie

MiB Swap:   2048.0 total,   1325.5 free,    722.5 used.    157.1 avail Mem 

I'd really appreciate any help with this. I'm at a loss.

Redash is pretty much unusable for us without scheduled queries working. Is this project dead?
