This is a well-known issue. Several memory structures are leaked on each
configuration file reload.

See https://www.stunnel.org/sdf_todo.html
  - Deallocate SERVICE_OPTIONS structure when the configuration file
    is reloaded *and* old connections are closed.

Would you like to sponsor implementing reference counting of the
SERVICE_OPTIONS structure?

Best regards,
