Some of the messages may have multiple interpretations, but the overall pattern is understandable. By experimenting with the configuration and seeing what kinds of error message are produced, we can gain a feeling for how to interpret the entries in the error log.

Understanding what is going on at the TCP level will help when tuning these parameters to meet the load under real conditions. Rounding off our tour of troubleshooting, we saw what kind of information the stub_status module was capable of delivering. This data can be useful for...
