Error description

  • Approver Initials:    RP
    Reported Release:     622
    PROBLEM DESCRIPTION:
    
    When monitoring log events from an agent, and the event rate is
    very high, multiple events can be merged into a single buffer by
    proxy before they can be sent to the data server.  If the event
    rate is high enough, the buffer can grow large enough to cause a
    Monitoring Server crash.
    
    
    RECREATE INSTRUCTIONS:
    
    The crash is very difficult to recreate.

    ****************************************************************
    When monitoring log events from an agent, and the event rate
    is very high, multiple events can be merged into a single
    buffer by proxy before they can be sent to the data server.
    If the event rate is high enough, the buffer can grow large
    enough to cause a monitoring server crash.
    

Problem conclusion

  • Use explicit memory request so that if the request fails, a
    decisive action can be taken to avoid the crash.
