Example error log is attached. At least to me, it is not obvious what is happening.
When do you need this? (YYYY/MM/DD) 20-08-2018
When is this no longer needed or useful? (YYYY/MM/DD) Always useful
If we cannot complete your request, what is the impact? Copr will have only few working builders avaialble because new builders cannot be spawned.
Additional note: You can check /var/log/copr-backend/spawner.log for the full logs from the spawner process.
Restart of copr-backend service helped.
Hopefully this is back to normal now.
