Hello,

What's the best way to deal with this send/receive error?

Hello,

Typically get a new kernel where this is fixed, Filipe has been working on fixing them.
What kernel was this on?

Send box is 3.16.6 . Receive box is 3.17.4 .

Just upgraded the receiving box to 4.0.2 which didn't fix it, so I'll schedule a reboot of the sending box.

Yeah, usually these problems are because the sender sent a sequence of events that doesn't make sense and can't be replicated by the receiver. Hopefully the server upgrade will fix it.

Otherwise Filipe will be very interested in getting the output of btrfs send -v -v from the sending and receiving side just around the time where it dies.

The kernel upgrade on both ends fixed it. Thanks Marc, Filipe.
