    z3950 server returning communication failure

    • Article Type: General
    • Product: Aleph
    • Product Version: 20, 21, 22, 23

    Problem Symptoms:
    The $LOGDIR/z39_server_9991.log file  has:

    z39_server(1) [warn] Scan: communication failure (code -5)
    ERROR 2+ Temporary_system_error 0 - 1+

    or
    z39_server(425) [warn] Search: communication failure (code -7)
    or
    "Search was a bloomin' failure"  or  "connect: Connection refused" errors.

    Cause:
    1) In $alephe_tab/z39_server/z39_server.conf, the pc_server port number was incorrect.
    It is currently set to:
    hostname localhost:6991
    While your pc_server port is "6992".
    2) The pc_server which should be running on the port specified in $alephe_tab/z39_server/z39_server.conf file is not running or is blocked.

    Resolution:
    Check/correct the port number and restart the z39_server and the pc_server.
