[Samba] NT_STATUS_WRONG_PASSWORD with multiple concurrent connects from same IP Address.

We are having a problem with SAMBA v 3.0.13 on Linux where a windows client
(single IP address) makes multiple connections at the same time
(different processes) to copy files onto our SAMBA server.  As many as 20
simultaneous connections/file transfers may be occurring from the
same client IP address.

Some of the files succeed, and some fail.  The windows client reports
that the directory does not exist...

All copies are done by the same user id, but are running as separate
processes on the windows server (Therefore, I believe, separate
authentications for each).

I have turned on Log level 2, and see the following message in my log
file for the failed attempts:
[2005/03/30 14:33:03, 2] auth/auth.c:check_ntlm_password(307)
 check_ntlm_password:  Authentication for user [det-liv-cd1] ->
[det-liv-cd1] FAILED with error NT_STATUS_WRONG_PASSWORD

Just prior to, and right after these error messages, there are messages saying that the user ID and password were accepted! 

det-liv-cd1 is a local user id, and this same user ID is used for all
the transfers.

We've tried changing the max mux setting 5000, and this seems to
reduce, but not eliminate the number of failures.

Any Ideas what may be happening?...or what we could look at next to
try to resolve this problem?
