I made a small mistake when i copied the prefork parameters from the webui to the cache service API server. The webui has an Apache reverse proxy to handle HTTP keep-alive connections, but the cache service does not.
That means when a worker is under heavy load you can start seeing errors like
[2020-01-17T11:29:56.0370 CET] [error] [pid:47664] Unable to setup job 3801895: Cache service not reachable: Inactivity timeout
, because other workers were blocking access to the API server with their keep-alive connections.
