The root cause is related to locked - portal required- entities.We found two databases where DATABASECHANGELOG tables values must be flushed. 

mysql> update DATABASECHANGELOGLOCK set LOCKED=0,LOCKGRANTED=NULL,LOCKEDBY=NULL where ID = 1; 

Process must be applied to rbac and portal databases (first we flushed only the portal database databasechangeloglock table, which is not sufficient). 

We validate the fact that the issue is fixed by restarting several times the portal.
