I have a packet trace from the last time I observed the problem. It shows normal NFS traffic culminating with a successful FSSTAT operation. Then, the client sends alternating EXCHANGE_ID and CREATE_SESSI= ON operations, but the server never replies. It does send TCP ACKs, but there= is no NFS-level response. It does continue to service other clients normally. I am unsure how to debug this further, but I can probably conduct any experiment you suggest. I can also provide the pcap files if necessary. --=20 You are receiving this mail because: You are the assignee for the bug.=
