Winbind memory leak on RHEL 3?

Any help or pointers would be really appreciated - I'm stumped by this:

We have stock RHEL 3 systems that use Winbind to authenticate users against Windows 2000 Active Directory servers. This works OK, but the winbindd processes will occasionally start to consume increasing amounts of memory without limit. Restarting the winbind service resets the memory use back to normal levels.

Winbind is set to run in double daemon mode with the option in /etc/sysconfig/samba, and the smb.conf files look like this:


# Optimum Samba performance settings
socket options = TCP_NODELAY

# NT workgroup settings
workgroup = OURDOMAIN
server string = Samba Server

# WINS network browsing settings
# All functions disabled apart from using a WINS server for lookups.
local master = no
domain master = no
preferred master = no
wins support = no
wins server =
dns proxy = no

# Active Directory member
security = ADS
password server = ms-dc-01.ourdomain.local, ms-dc-02.ourdomain.local

# Enable Winbind for AD and local account synchronisation
winbind separator = +
winbind use default domain = yes
idmap uid = 10000-25000
idmap gid = 10000-25000
winbind enum users = yes
winbind enum groups = yes

# Defaults for local accounts created by Winbind
template homedir = /home/%U
template shell = /bin/nologin

# Logging settings
log file = /var/log/samba/%m.log
max log size = 5000

# Printer sharing
printcap name = /etc/printcap
load printers = no

I've set the options in nscd.conf to disable caching:

passwd: files winbind
shadow: files
group: files winbind

The /etc/krb5.conf files vary: one server may use DNS to locate KDCs, another is more strictly configured to use two specific servers as KDCs.

Thanks for reading this far!
