It depends on the context. Here we called __createMailboxMontior, which is something we call when creating an instance, and is marked as @unsecured. This call is calling now a new helper introduced in 7cf19dafd7cd, but the helper was not marked as @unsecured. This will raise UnsecureError, which will fail the current flow. We have another instance of this during upgrade domain flow - I think we have the same issue there, but this needs investigation.

Other errors means that a real secured method is called when a host is not hte spm. This may be bad client code, or unavoidable, since there is no race-free way to check that a host is the spm before calling a method on the spm.
