Hi Anjana!

One way to workaround the problem with SFTP and large files is to add
the -Xmx256M (or appropriate) to your java start command to allow the
jvm to reserve more memory, but for sure, the OOM exception will come
back with larger files then.

Hmmmm ... could you please paste a "full stack trace" [1] when vfs stop
copying, I assume it hangs at all, no?
That stack trace should give us a clue where it hangs.
Which version of JSCH do you use? Maybe upgrading to the latest version
will help.


Ciao,
Mario
