The ouptut you're getting with $ssh2->scp_get($old, $new) differs quite markedly from what I get. I'm running with $ssh2->debug(1);, and I gather you're doing the same ?

My particular code segment, which is doing the job fine, is as follows: 
for(@files) {
   $ret = $ssh2->scp_get("$dir/$_", "$_");
   print "RET: $ret\n";
}

My @files contains 6 filenames, and the output that segment produces is:

I'm thinking it's the Net::SSH2::Channel::DESTROY that occurs between successive scp_get() calls that might be critical. I'm using Net-SSH2-0.19 (built against libssh2-1.0).

I haven't tried grabbing large numbers of files - and if I did, then faik I might well strike exactly the same problem as you.

Cheers,
Rob
