  • Groups view performance issues after upgrading to CU6 from CU5.
  • MS SQL Server cpu utilization seems high as well.
  • Selecting group view and clicking alarms or maintenance ends up freezing up any browser.
data_engine.log shows
de: COM Error [0x80040e31] IDispatch error #3121 - [Microsoft OLE DB Provider for SQL Server] Query timeout expired

...seems related to the problem.  It makes no difference if you use the old default data_engine provider or the OLEDB provider, both generate the "timeout" message in the log.

When working on a lot of dashboards - the response time is sometimes terrible. 

It's almost the impression that some new code is "locking" the sql database.


  • Release: 20.4 CU6


  • Defect in CU 6


  1. Installed updated ump_operator_console 20.49 to the Operator Console machine (ump_operatorconsole-20.4.9.zip)
    (can be found here https://support.broadcom.com/web/ecx/solutiondetails?aparNo=99111691&os=MULTI-PLATFORM)
  2. Increased SQL Server Max memory
  3. Increased maximum memory for the discovery_server
  4. data_engine command_timeout set back to 150
    • This can be added to the data_engine <setup> section.
      command_timeout = 300
      This setting helps to avoid timeout issues during data_engine INSERTs to the backend UIM database.
  5. Deployed new discovery_server v20.44T1 to the robot that owns the discovery_server probe (it is attached to this article).
