Dear Monks,


I have a perl script which copy files via scp (and open3) from one server to another. After copying, some tasks have to be run remotely (by the sending server): it could be untarring an archive, or moving the file to another place.


Overall, it works nicely. But when i transfer a file greater than a given size (somewhere around 30M it seems) then the file transfer works correctly, but the following tasks (launched by another call to open3) doesn't catch an EOF on STDOUT.

Related code :

  my $pidscp = open3(*HIS_IN, *HIS_OUT, *HIS_ERR, $configTransferBin, 
+@args);
  my @outlines = <HIS_OUT>;

With smaller files, the script will go further.
With bigger files, it just hangs here ( I've tested by let it run for more than 1 hour). The output isn't verbose at all : at worst, stdout should get only 3 or 4 lines), and the size of the datas sent to STDOUT by the remote command doesn't depend upon the size of the actual file.

Any of you ever faced an issue like this one?

Thanks in advance.
