| ERROR | timed out waiting for responses from servers |
| CAUSE | Not enough servers are running to handle the current system load, and a large backlog of commands has accumulated; perhaps no servers are running. This message could also indicate an internal error where one of the servers has crashed trying to process a given request |
| ACTION | Check that enough servers are running, and that they are processing commands of the correct type. For instance, a DDL command might timeout if all the servers are setup to exclusively process query commands. Also, check the server log files. |
