When copying files to my Samba server approximately > 100 MB from windows xp/2000 machines I get an error message saying that the network path is no longer available after a minute or so of copying. I can copy files > 100 MB from the Samba server to the same machines with no problems. I can copy any number of approximately < 100 MB files to the to the same Samba server. Linux machines can send and receive files of any size and number. I have other Samba servers running that do not have these problems and I copied the smb.conf's from the to this server but the issue remained. This Linux instalation is in an iSseries guest partition using nat subnetting via virtual networking. All other systems such as FTP, SSH, telnet, HTTP are working as expected. I matched the MTU's of the virtual and the line descriptions to be 1496. My config allows guest access with security=share so there are no security issues and the file system permissions are wide open also.
My Samba log is filled with the following messages: [2004/08/26 15:31:09, 0] smbd/oplock.c:request_oplock_break(1244)
request_oplock_break: no response received to oplock break request to pid 28509 on port 45506 for dev = 7001, inode = 4096
Thanks for your attention and if any more info is needed i will provide asap.
