Memory leak in ZFS Storage Appliance driver

As you may remember, one of my first posts was on an outage with our 7420 ZFS array, so you may need to know about MOS note 1635002.1 for "A Memory Leak in the nxge(7D) Driver for ZFS Storage Appliance Software May Cause ZFS Storage Appliance Service Outages" as it sounds a LOT like the situation I encountered years ago.  The good news?  It affects several versions of the ZFS appliance, but they all end in 10 and not 20, so I know this isn't something new that we have to worry about for our installation!
