[Samba] Samba 3.6 issues

[wong lmark]

Dear Samba Team,

There are three issues happening in my Samba 3.6.6

Issue 1: After upgrade, when upload file which is more 100mb to Samba, it
shows error "File name too long cannot copy" in windows xp. Tried to use 3
different pc to upload different files more than 100mb, it also fail to
transfer the file and show the error. Tested to upload file which is 25mb
or 50mb, it is okay, no problem . Before upgrade the samba 3.6, I am using
samba 3.0.28.

Issue 2: Users could logon to the pc within the domain, but the network
drive could not be mapped from 15-7-16 after 18:00 around (e.g.
\\dc01\netlogon). And the network drive could not be mapped through net use
command in windows xp. Also, the trust relationship with anthoner domain
chb lost. Attached the samba log and error screen capture for reference

Issue 3. When enter the command "service smb status", it show many process
id, is it normal?

Thanks for your help.
