      Description

      When a TCP/IP Stack on a z/OS system running Derby is stopped and started, Derby loops with the following stack trace repeated until disk space is exhausted on the logging file system:

      Wed Jul 20 07:49:51 CDT 2011 : EDC5122I Input/output error.
      java.net.SocketException: EDC5122I Input/output error.
      at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:457)
      at java.net.ServerSocket.implAccept(ServerSocket.java:473)
      at java.net.ServerSocket.accept(ServerSocket.java:444)
