Fix OptimisticLockException

✅ Solution

OptimisticLockException in Keycloak usually arises from concurrent transactions attempting to modify the same database record, violating the optimistic locking strategy. To resolve this, implement retry logic with a short backoff period around the failing transaction, or synchronize access to the affected entities to prevent concurrent modifications. Consider also investigating if database transaction isolation levels can be adjusted to reduce contention in specific scenarios, mindful of potential consistency trade-offs.
