Event ID 100 is continuously generated on the Discovery Accelerator (DA) server after deleting a case with legal holds applied.
In the Event Log:
Source: Accelerator Service Processor
Event ID: 100
Customer ID: X - An error has occured when initializing the Cases. System.Data.ConstraintException: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints
While deleting a case with legal holds applied, an attempt to place an invalid NULL in the LegalHoldState for a case is rejected. This action is preventing legal holds from being properly removed on items in the Vault Stores and items removed from the Review Set table in Discovery Accelerator (DA).
Remove legal holds from a case prior to deleting the case.
This issue has been addressed in the following releases:
Discovery Accelerator 8.0 SP5
Discovery Accelerator 9.0.1
