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.

Problem summary

• MANAGEMENT SERVER CRASHES DURING HIGH EVENT RATE
  
  
  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.
