Error description

  • When the queue manager error log AMQERR01.LOG gets full, then
    it rolls over to AMQERR02.LOG and then AMQERR01.LOG becomes
    empty and starts getting new messages.
    
    If AMQERR02.LOG is full and needs to roll over, it should do it
    to AMQERR03.log.
    
    But the rollover from AMQERR02.LOG to AMQERR03.LOG is not
    happening.
    
    The symptoms also include missing log contents for some period.
