I'm facing a strange major issue with scp. The issue exists in all cygwin version later than 3.5.3,
including cygwin-3.6.0-0.374.g4dd859d01c22.

If I'm copying a large file with scp I get a "connection lost" after a random couple of seconds:

scp -v large_file foobar:
.
.
debug1: Sending subsystem: sftp
debug1: pledge: fork
large_file                                             10%   71MB   4.3MB/s   02:21 ETA

Bytes per second: sent 6035219.0, received 2317.9
debug1: Exit status 11
lost connection

This is reproducable.


The strange thing, if I use strace to debug this, the cpoy succeeds:
strace -efno strace.log scp -v large_file foobar:
.
.
debug1: Sending subsystem: sftp
debug1: pledge: fork
large_file                                                                                                                                                                                        100%  678MB   6.0MB/s   01:53

Bytes per second: sent 6237052.6, received 2230.0

And this is reproducable too.

I would try to debug this further, if I had an idea how to do that.

Any thoughts?

Regards

Rainer
