The solution (for those that may find the information = of some value) was to set the value for kern.ipc.nmbclusters to a higher = value than we had initially. Our previous tuning had this value set at = 25600, but following a recommendation from the good folks at iXSystems = we bumped this to a value closer to 2000000, and the 4-port lagg is = functioning as expected now. Thank you all. Joe
