C200-M2 Qlogic HBA keeps re-sync


I have the following setup

-NetApp Storage

-2 x UCS C200-M2

-Qlogic HBA 4Gbps dual port "QLE2462"

-2 x mds 9124 running 5.0(1a)

The NetApp is stable and and apparently no problems, but one port of each HBA area constantly loosing connectivity, I'm also receiving several OLS and NOS messages

SOERAD-FC-9124-01# sh int fc1/5

fc1/5 is up

And this keep's increasing....

I have replaced the Patch and nothing, could this be a firmware problem ?  I have looked also at bug navigator and nothing close to this....

Should I consider a FW upgrade ? currently I'm running c200.

Kind regards,

Just to confirm you've changed all cables and transceivers in the path?
