  • Closed as program error.

Error description

  • On rare occasions a shipping_server (sender) may hang, and never
    complete.
    It does this after sending its data, but before logging success
    to the local shipping_server_log.
          The completion of the data transfer is logged at the
    receiving site.
    
    The hung process could have been initiated by any of
        shipping_server -poll
        mkorder -fship
        syncreplica -export -fship
        mkreplica -export -fship
    
    When this occurs as part of a scheduled job, it can hang the
    scheduled job and prevent repeat jobs from being submitted.
    

Local fix

  • The system administrator (root) needs to kill the hung
    shipping_server process.
    
    To check for hung process do
    >    ps -eo pid,etime,time,args | grep shipping_server
      PID     ELAPSED            TIME COMMAND
    15704  dd-hh:mm:ss       00:00 shipping_server  sh_o_...
    
    An elapsed time of hours or days would indicate it is hung
