[Samba] Binary filenames in smbstatus output? (Samba 2.2.5)

[Henry, Brad ERM]

Have any of you seen behavior like this before? We are currently having
problems with our Samba server coming up telling a lot of our users that
Word files "are locked for editing." and will only let users open them Read
Only. 

We are running Samba 2.2.5 from standard RedHat 7.2 RPMS, on i386 RedHat
7.2, Kernel 2.4.9-34smp. Im putting this to the list as a symptom to see if
anyone has ever seen similar behavior. 

Please let me know if you have any suggestions. The server is in production
and so we are a little apprehensive of changing versions unless we can be at
least fairly certain the change will be painless and going to fix our
problem.

Partial output of smbstatus' locked files section shows:

13848 DENY_NONE 0x20189 RDONLY NONE z~ Tue Jul 15 10:17:26 2003
13848 DENY_WRITE 0x20189 RDONLY NONE z~ Tue Jul 15 10:17:26 2003
11705 DENY_NONE 0x20189 RDONLY NONE z~ Tue Jul 15 09:59:57 2003
11705 DENY_WRITE 0x20189 RDONLY NONE z~ Tue Jul 15 09:59:57 2003
29695 DENY_NONE 0x20189 RDONLY NONE z~ Tue Jul 15 08:11:32 2003
29695 DENY_WRITE 0x20189 RDONLY NONE z~ Tue Jul 15 08:11:32 2003
16678 DENY_NONE 0x1 RDONLY EXCLUSIVE+BATCH
/data/ep/wq/windat/windat/CONFIGUR.DAT Tue Jul 15 10:36:44 2003

The file named z~ worries me.....there are also entries like %, ~ and 8.
Being that it is not showing path information it seems odd, can anyone
explain this behavior? I can produce my smb.conf and high level debug output
offlist if anyone thinks they can help.

Thanks alot,
Brad
