Hi,
to enable the vprotocol pessimist, you have to specify -mca vprotocol
pessimist. This parameter takes precedence on the priority. Let me
know if you hit success :]

Hi All,
I´m trying to use the pml_v (pessimist) with FT components, but during
the loading the pml_v closes and close the vprotocol_pessimist too...
according the following:
