I am having the same issue and this worked for me so far but needs more testing. I was able to copy 12gb w/o a lock-up and another 12gb about 8 hrs after that. The real test for me is to copy 12gb and another 12gb within a shorter time window. I’ll try to complete this later tonight.
UPDATE: I was able to copy 61.3gb of data in a 90 minute window w/o one single lock-up. I should also state that I am using a WBEII WL connected to the network so this doesn’t appear to be the same setup as described in the thread. My apologies but I hope this information fixes your issue too.
Thanks for the advice on the NIC configuration. Much appreciated.
