When you simultaneously remove multiple groups from a user’s membership in SAS Visual Investigator Administrator
(https://<VIYAHOST>/SASVisualInvestigator/admin.html#/permissions), multiple email records can be created for the same user.

This behavior leads to the accumulation of duplicate entries for email, which in turn can cause excessive memory consumption by the sas-identities pod. As memory usage increases, the identities service might restart repeatedly, which ultimately results in application instability.
