Purpose
Troubleshooting the error "No more data to read from socket" error can be challenging, because there are a variety of potential causes across multiple parts of the overall environment. Generally, this error happens when the application expects data to be present on the socket that is not there. The exception does not explain why there is no data on the socket, and neither does any accompanying Java exception stack on the application side. It can happen when attempting to establish a database connection, or it can happen after a connection is already established.
The following list categorizes and enumerates areas to check that have been known to cause this problem, referencing a variety of notes that detail specific use cases. The list will be updated and revised as new findings come to light.
