After certain HP-UX patches are applied, clients such as SAS^® Management Console, the Flow Manager in the Platform LSF Process Manager, and commands (for example, jid) that attempt to communicate with Process Manager might fail. Possible error messages include server not available and connection reset, as shown in the following command prompt:

# flowmanager
[A dialog box appears, containing:]
Java.net.ConnectException: Unable to connect to Process Manager.
# jid
Process Manager server not available.
# jkill 1234
java.net.SocketException: Connection reset

The underlying problem is the fact that jfd (the Process Manager daemon) does not read all messages from the TCP/IP buffer, leaving the server always in a receiving (RECV) state. That is, the server writes a message back to the client over the same socket and then closes the socket with the server in the RECV state. As a result, the buffers are not properly flushed and TCP/IP resets the connection to correct this state. This action leaves the client unable to continue communication with the server.

Currently, there is no workaround or solution for this problem.

If you are running Platform Process Manager 3.0, select the Downloads tab to access the patched jfd and updated client files.
