quarkus: GRPC / Panache Reactive Combination causes issues after a couple requests

Describe the bug When invoking Panache Entities via a GRPC Service in a reactive way, the first couple invocations will work but after that all that happens is a “java.lang.IllegalStateException: session is currently connecting to database”

Expected behavior The Panache invocations work until the end of the universe.

Actual behavior After a couple of invocations only “java.lang.IllegalStateException: session is currently connecting to database” is produced. HealthChecks will also fail if present in the project.
