Subject DO NOT REPLY [Bug 44834] New: SimpleSocketServer looses buffered logs, produces spurious error on exit.

           Summary: SimpleSocketServer looses buffered logs, produces
                    spurious error on exit.
           Product: Log4j
           Version: 1.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Other
        AssignedTo: log4j-dev@logging.apache.org
        ReportedBy: bernard.stumpf@verizon.net


Running SimpleSocketServer.java receiving logs from other nodes, configured via
XML, using RollingFileAppender with "BufferedIO" value="true", "BufferSize"
value="65536", upon socket close from the sending side the buffered logs are
lost.

Since SimpleSocketServer is a main program it is responsible for calling
LogManager::shutdown() as stated in the log4j documentation.

The lost logs problem is easily corrected by reconfiguring to do "BufferedIO"
value="false", but that defeats the performance purpose of buffering on the
server side.

The spurious error on exit was:

2008-04-15 18:16:19,410 [Thread-0] INFO  org.apache.log4j.net.SocketNode
(org.apache.log4j.net.SocketNode.run(SocketNode.java:89)) - Caught
java.io.EOFException closing conneciton.

Note also the misspelled "conneciton" in SocketNode.java (in three places)
