APAR status

  • Closed as program error.

Error description

  • MaxChannels attribute is the maximum number of channels that can
    be current. When current defined maximum number of channels
    value is crossed, AMQ9513 error message is logged.
    
    AMQ9513: Maximum number of channels reached
    
    But the above error message doesn't specify the current
    'MaxChannels' value.
    

Local fix

  • One way to check the current 'MaxChannels' value being used is
    by dumping the values in a FDC. On windows platform 'amqldbgn'
    command can be used to generate a diagnostic FDC.
    
    usage: amqldbgn -p PID
    or
    kill -USR2 PID (on UNIX platforms)
    
    In this particular case for 'PID' use the amqrmppa process ID
    which will generate an FDC against the amqrmppa process which
    will dump 'MaxChannels' value.
