Users may note that after populating dynamic groups in USM, the groups may appear to de-populate. For several minutes, the groups may appear to be populated correctly, and then intermittently drop to 0 members.
Additionally, the UGS probe may be seen to generate SQL queries that consume large amounts of CPU on the database server.
Other symptoms may include:
In UIM 8.4, the UGS probe has been replaced by a probe called Trellis which resolves these issues.
We have created a version of the Trellis probe that is compatible with UIM 8.31, with the exception of NetFlow Analysis (NFA) Integration. A USM hotfix is also required.
Users relying on NFA Integration with UIM/UMP should upgrade to UIM/UMP 8.4 rather than applying this hotfix. The hotfix will break NFA integration in 8.31 and this cannot be resolved.
Additionally, the health_index probe will be removed by the hotfix; customers who rely on this functionality may follow some additional optional steps to re-enable this functionality in 8.31. Customers who are not using health_index do not need to apply these steps.

Instructions for re-enabling the health_index functionality are included in the PDF located here.
