Occasionally, I see errors like this when calling `rdctl shutdown`:
Copy code
WARN[0000] instance "0" has errors                       errors="[host agent is running but driver is not]"

The "invalid username/password" error is unlikely to come from Rancher Desktop but from your schema creation tool. I have no idea how to debug that part, as I don't even know what tool it is.
I would check if the Rancher Desktop VM and container engine is still running at that point
What do you get when you run
docker ps
or
docker images
?
g
well…. the tool’s error message might be misleading but it is unable to connect to the database
the VM is running
starting RD allows it to connect again for a dozen or more runs
f
Does
rdctl shell
still work?
g
then it starts failing and restarting RD eliminates the problem
good question, I will try that next time it happens
my guess is yes
f
I wonder if it is maybe failing due to memory pressure; did you try giving the VM more memory and see if it runs for longer that way?
g
that is something I can try. However, there is only either 0 or 1 container running
I have given RD 2 CPUs and 6 GB of RAM
f
That may not be enough depending on your application. It may consume too much memory and the Linux out-of-memory killer may start killing random processes which in turn breaks the base functionality. Worth trying to use more

ok
