winbind 3.3.7 memory usage

[Dr. Hansjoerg Maurer]

Hi

I am running 3.3.7 on Centos-4 and Centos-5 (both x86_64) and I observe
a continuous growing memory usage of winbind, so that I have to restart
winbind every few weeks


[root at rmcs31 ~]# psgrep winbind
root     10654  0.0  0.1 303984  4632 ?        Ss   Aug26   1:29 winbindd
root     10655  0.0  0.3 356824 12628 ?        S    Aug26   0:57 winbindd
root     10669  0.0 23.0 2827472 931052 ?      S    Aug26  14:51 winbindd
root     10670  0.0  0.0 302884   752 ?        S    Aug26   0:00 winbindd
root     10751  0.0  0.0 302896   364 ?        S    Aug26   0:00 winbindd
root     10769  0.0  0.0 304888   636 ?        S    Aug26   0:00 winbindd


and one week later

[root at rmcs31 ~]# psgrep winbind
root     10654  0.0  0.1 303984  4472 ?        Ss   Aug26   2:26 winbindd

The samba Servers are member of an Active-directory Domain
        security = ADS
        idmap backend = nss
        idmap config YYY : backend  = nss
        idmap config YYY : readonly = yes

The unix systems are integreted into AD with Vintella Authentication
Services from quest.
Winbind is only used for mapping  AD-Users to Unix-Users.

Is this a hint for a memory leak in winbind and (how) can I provide some
debug/trace information?
