scp large file: broken pipe + Limiting closed port RST response

[Chris Stankevitz]

Hello,

Regarding this setup:
- two identical computers with Intel I350 gigabit ethernet
- single ethernet cable connects both computers
- one computer using scp to copy a 500 GB file to the other (~100 MB/sec)
- 9.2-RELEASE-p10 (FreeNAS)
- scp -o NoneSwitch=yes -o NoneEnabled=yes /path/to/file root@10.1.1.2:/path/to/file

1. Why does the scp connection fail ~10 minutes into the transfer with "broken pipe"?

2. Why does this transfer generate log entries like the following:
Limiting closed port RST response from 1235 to 200 packets/sec
Limiting closed port RST response from 1288 to 200 packets/sec
Limiting closed port RST response from 1298 to 200 packets/sec
Limiting closed port RST response from 759 to 200 packets/sec
Limiting closed port RST response from 293 to 200 packets/sec

3. Could (1) and (2) be related?

Thank you,

Chris
