scp_put failing when there are too many files

[Ori Raz]

Hi,
Did anyone encounter the scenario where scp_put is failing (too many
arguments) when the directory contains too many files?
We have 36K files in the directory and it is failing... (with lower amount
it works fine)

This is how we use it:
$dr_node->scp_put( { recursive => 1,
glob => 1,
copy_user_attrs => 1 } ,
"$ib_backup_path/*",$ib_backup_path );

And we get the error:
Can't exec "rsync": Argument list too long at
/perl/lib/perl5/site_perl/5.16.0/Net/OpenSSH.pm line 1433

Appreciate any advise :)

Thanks.
