Hi Min,
The transfer failed after 9h43 / 880GB.
I'm going to restart it and snoop to a file in the hope I see something.
If you have some dtrace script to see what's going on or some system
setting to get logs of what might be going on, I would be more that
happy to test it.
Thanks,
Arnaud

Hi Min,
I had problems with build 130, and saw that the e1000g driver was
updated in 131. That's why we updated.
I haven't tested with previous builds and was not that extensive with
my tests in 130, so I cannot tell wether it's the same problem or not.
The kstat command returns
Reset Count 0
Reset Count 0
on both nodes.
A colleague of mine connected the two machines back to back (I'm at
home, sick, not at work).
I restarted the transfers that failed last night, I'll keep you posted
about it (already done 50GB).
I know this switch (HP 4208) doesn't support jumbo frames, so I
haven't enabled jumbo on the nodes.
If this tranfer works, could this mean our switch is kind of broken or
buggy ?
Regarding the replacement with other builds, I can do it on the
receiving end, but not that easily on the sending end (the one that
"looses" the connection).
Thanks,
Arnaud

Hi Arnaud,
On which build you started to notice the issue? Could you still ping
through when you noticed the error? What's the output of "kstat -m
e1000g |grep Reset"?
Recv_Length_Errors indicates the packets received are undersized(< 64
bytes) or oversized (> 1522 bytes when jumbo frames aren't enabled).
I expect to narrow down the issue by simplying the network
configurations You mentioned the two machines are connected via a
switch. Could you try to have the two machines connected
back-to-back? Further more, Could you try to replace one machine with
other builds/OSs?
Thanks,
Miles Xu

Hi folks,
My situation is the following : 2 computers (A and B) running
Opensolaris b131 having intel 82574L NICs, connected through an
HP4208 switch.
Both computers are on the same network.
I have transfers running from computer A to computer B, either
through ssh or netcat.
As long a computer B is not too busy, the transfer goes like a charm.
But when B's really busy (doing zfs recv from a local file in this
case) , the transfer fails is an odd way after some time (tests show
somewhere between 10 minutes and 13 hours).
What's odd is that A reports that he could not read from B and
closes the connection (no sign of it in netstat), but B still thinks
the connection is open.
Further, running "kstat -p | grep e1000g | grep -i err" on A show
all zeroes but for the following :
e1000g:1:statistics:Recv_Length_Errors 14
link:0:e1000g1:ierrors 14
e1000g:1:mac:ierrors 14
More details on the test cases is available there :
http://opensolaris.org/jive/thread.jspa?threadID=122977&tstart=0
You can see that Brent Jones mentionned the following CR but this
is marked as a dupplicate of something fixed in 131.

I did not do any twiddling in e1000g.conf.
Both e1000g are grouped in a aggregation named trk0.
Per advice of Richard Elling, I disabled LACP and, just to be sure,
I unplugged one network cable on each machine.
If any of you has any clue or workaround to try, please share.
Thanks,
Arnaud
