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
