Why does my container repeatedly restart on a raspberry pi?

Stuck with a misbehaving container, I tried adding a device variable DEBUG set to true
and ran this script

    if [ -n "$DEBUG" ]; then
        echo "debug set."
        while : ; do
            echo "Idling..."
            sleep 600

But I get a restart on the container every 20-30 seconds.

When I use the balena command on the Host OS, I see the container start, then quickly move to a state of Unhealthy, and then die, to be restarted.

What else should I look at?

Hi @jason10
It looks like you reached out to us using the support chat as well.

As I mentioned there, it looks like the supervisor is failing to update the service state after fetching a recent release.
We would need to run some extra diagnostics to understand the root cause (SD card corruption could be the one, but we need to confirm), so it would be helpful if you made the device online (it currently seems to be shut down).

I suggest we continue this conversation in the support thread you created.
