[jcifs] jcifs.smb.SmbException: The handle is invalid

[Michael B Allen]

Hi René,

This probably means pretty much what the error text suggests. My guess
is that, because you are crawling, you probably started a list
operation and then left it open for a long time but by the time you
came back to it, the server closed it due to resource pressure. Of
course that is wild speculation but that is the sort of thing that can
cause this class error. When you crawl, you want to make sure you keep
your file stack small (meaning do a breadth first search as opposed to
a depth first search).

Otherwise, make sure you're using the latest JCIFS. Prior to rewriting
transport locking, one user experienced a significant improvement in
this class of error.
