Hi :
Thanks for your quick reply.
I downloaded the most recent jsch yesterday jsch-0.1.30.jar and that was
the one that generated the error.
I was closing my FileObject after I got what I wanted so I could trick
the cache. I think this may have been
part of the problem.
I have refactored things and use my own DefaultFileSystemManager with
the default CacheStrategy also I
close this FileSystemManager on contextDestroy (when I "undeploy"). I
think/hope this permits Tomcat
to release the references associated with the FileSystemManager.
I haven't seen the exception again (my fingers are crossed).

I've never seen this exception.
Hmmm ... just to be sure, did you already tried the version 0.1.23 we
use with VFS [1].
Just to sort out the problem, could you please do so, if this works it
might be a bug in jsch and we have to dig into their code, or report it
on their mailinglist.
Thanks!
Ciao,
Mario
