But did you notice the network log: 07:02:07.481323 yeti.csihq.com.686186576 > picard.csihq.com.nfs: 1472 write [|nfs] (frag 28948:1480@0+) 07:02:07.481446 yeti.csihq.com > picard.csihq.com: (frag 28948:1480@1480+) 07:02:07.481569 yeti.csihq.com > picard.csihq.com: (frag 28948:1480@2960+) 07:02:07.481692 yeti.csihq.com > picard.csihq.com: (frag 28948:1480@4440+) 07:02:07.481814 yeti.csihq.com > picard.csihq.com: (frag 28948:1480@5920+) 07:02:07.481886 yeti.csihq.com > picard.csihq.com: (frag 28948:916@7400) 07:02:07.482321 picard.csihq.com.nfs > yeti.csihq.com.686186576: reply ok 136 write [|nfs] (DF) 07:02:07.482511 yeti.csihq.com.702963792 > picard.csihq.com.nfs: 108 commit [|nfs] (DF) 07:02:07.482642 picard.csihq.com.nfs > yeti.csihq.com.702963792: reply ok 128 commit (DF)
The file is being copied from yeti to picard. Last packet seen is picard telling yeti "OK" after the commit. If soft timeouts were occurring shouldn't we be seeing packets from yeti again with no response from picard?

According to the 'nfs' manpage, the default timeo on the mount in util-linux is usually 0.7 seconds. retrans is 3.
0.7 + 1.4 + 2.8 = 4.9 seconds < 10...

I think it does.
