Were you able to resolve the cause of this? I found this thread today when one of my servers started having the same problem. Hard lockups with the nearly the same message on the console.
My affected server is a Supermicro 6037R-TXRF with the X9DRX+-F motherboard. It has 2 Intel nics. The console message reads: received unsolicited ack for DL_UNITDATA_REQ on igp0arl_dlpi_pending It repeats 4 times and the system locks. This system is completely unloaded and the problem occurs after only a few minutes of uptime. Thanks for any additional info you can provide. -Chip On Thu, Mar 21, 2013 at 3:53 PM, James Carlson <[email protected]>wrote: > On 03/21/13 14:14, Pico Aeterna wrote: > > James, > > > > Thanks for the reply and the dtrace hint. > > > > # dtrace -n 'fbt::arl_dlpi_pending:return/arg1==0/{stack();}' > > dtrace: description 'fbt::arl_dlpi_pending:return' matched 1 probe > > > > Pretty much this problem occurs when the system is under network load as > > it is the NFS store for about 5-6 vms via my ESXi server.
