Our authentication server runs on keycloak but every day we get a message like this:
2025-04-07 15:54:04,411 ERROR [org.keycloak.broker.oidc.AbstractOAuth2IdentityProvider] (executor-thread-101) Failed to make identity provider oauth callback: org.hibernate.exception.GenericJDBCException: Unable to acquire JDBC Connection [Acquisition timeout while waiting for new connection] [n/a]
And the authentication server becomes unavailable. I noted that on startup, this error shows up:

What do you suggest I do to fix this?
