Problems with Preferred Fixed Path not staying on the fixed path even though no network/nic outage

Hi

We have a problem with the preferred fixed path not working properly to our "active/active" netapp storage, we set a datastore LUN preferred path and all of a sudden the host will go to a partner path with no warning or outage, then this will become the "*" preferred path, we have not changed this to become the preferred path and have to change it back as it's the non-preferred path general. Our datastores sit on a dual headed netapp.

We are using FCoE to storage & ESX 5.5 RU2

Anyone seen this and can offer help?

Cheers in advance.
