Fix OutOfMemoryError

✅ Solution

OutOfMemoryError in Keycloak often results from unbounded caching of JWTs, sessions, or other data, leading to memory exhaustion. To fix this, configure proper cache eviction policies by setting appropriate lifespan and max entries for realms, clients, and users using the Keycloak Admin Console or CLI. Also, review and optimize custom providers that might be contributing to excessive memory consumption through inefficient data handling or caching.
