SERVER FREEZE (event LSI_SAS event ID 129)

My production environment keep suffering from this issue, we have vcenter with 3 ESXi servers, all VMs and vcenter are on Netapp NFS share.
during the last two weeks our VMs start to freeze for couple minutes couple time a day, nothing changed..

i saw on the event viewer LSI_SAS warning event ID 129 (reset to device\raidport0 was issues) , so i upgrade the driver on all VMs to 1.34.3.82 from 3/26/2013, but looks like this issue continues to appear ..

my Setup is :
vcenter - 5.1.0
esx1 - 5.1.0
esx2 - 5.0.0
esx3 - 5.0.0

Our Netapp version is "NetApp Release 7.3.4P4"

pls help ASAP
thanks
