Hello !
I try to transfer a file to a windows 2000 share from a linux client with
jcifs. I use SmbFileOutputstream to transfer a large file (> 8GB).The
windows system can handle this file, because i uploaded it from here to the
linux computer.
I did an upgrade from jcifs 0.7.x to jcifs 0.9.7 which improved performance
but didn't solve the 4 GB problem. Transfer stops exactly at 4.294.963.200
bytes (Tried it several times). Is this a known issue ?

The Exception I get is:
jcifs.smb.SmbException: 0xC000007F
        at jcifs.smb.SmbTransport.send(SmbTransport.java:668)
