samba - Sep 2009 - Smbd process keep file locked

Guys
 
Can maybe someone help me to understand the nature of my problem.
 
1. I have Samba 3.0.32c with ADS on Solaris 9 server
2. Client run daily jobs from thr Windows which read data and write to
the log files on the samba share
3. Occasionally he started getting the problem that when job finished,
smbd process does not go away and lock the log file.
4. if I run trace on the process, it does nothing, just sleeps ...
 
It started few month ago without any changes from our end.
 
Here is from smb.conf:
 
[global]
        server string = Production Samba ver %v
 
        socket options = TCP_NODELAY
 
        workgroup  = GROUP
        realm = GROUP.XXX.XXX.COM
        security = ADS
        password server = server1, server2
        encrypt passwords = yes
        allow trusted domains = yes
        username map = /opt/local/samba2/lib/users.map
 
        log file = /opt/local/samba2/logs/log.%m
 
        locking = yes
        lock directory = /opt/local/samba2/var/locks
        pid directory = /opt/local/samba2/var/locks
        share modes = yes
        preserve case = yes
        short preserve case = yes
 
        smb passwd file = /export/nfs2/samba2/private3023c/
        private dir = /export/nfs2/samba2/private3023c/
        netbios name = sbtorsamba2
        name resolve order = host bcast
        domain master = no
        domain logons = no
        printing = bsd
        printcap name = /etc/printcap
        load printers = no
        interfaces = 192.168.253.85/28
        bind interfaces only = yes
        deadtime = 15
 
        preferred master = no
        local master     = no
 
        guest account = nobody
        guest ok = no
 
        syslog = 0

 
Sincerely,
Dmitry
