[gridsam-discuss] Problem using gridFTP

[Ismael M. C. <i....@fd...>]

Dear all,

I'm getting a random error when I use gridFTP for data staging-out. The
gridFTP is running as standalone (daemon flag is activated) and version
is 3.23.

The error stack is:

]".".".".".

This not happens using globus-url-copy client or even other java-based
clients making use of jglobus (1.6 and 1.8). No problems were found with
a batch of 400 requests (with a level of concurrency of 2 requests).
Also, the server uses a limited range of ports, while the client uses
any free port. Thus, I guess that some in the implementation of GridSAM
causes this problem.

Moreover, tracking the code, GridSAM 2.3 is using:

import uk.ac.nesc.vfs.gsiftp.GSIFTPFileProvider;
import uk.ac.nesc.vfs.gsiftp.GSIFTPFileSystemConfigBuilder;

and not the similar classes on
org.icenigrid.gridsam.core.plugin.vfs.gsiftp.*. Using these last classes
GridSam crashes before of establishing a connexion with the gridFTP
server.

Therefore, Could you tell me some workaround for this? or What is
version/s of gridFTP tested with GridSam? and eventually, Could I
download the java package uk.ac.nesc.vfs.gsiftp?

Best regards and thanks in advance.
