I'm running Samba 3.0.2a via Debian stable binary packages from samba.org, joined to Windows 2000 ADS domain. There was normally two running winbindd process after I installed Samba. I've noticed after a couple of days of running, when I run top - one process went defunct and the other starts to slowly use up memory:

PID   USER  PRI NI SIZE  RSS SHARE STAT %CPU %MEM TIME COMMAND
28085 root  9   0  27148 26M 2192  S    0.0  2.6  1:39 winbindd
28086 root  9   0     0  0   0     Z    0.0  0.0  0:00 winbindd<defunct>

As far as I can tell, there is no loss of functionality - I can connect to the shares, wbinfo -p succeeds and I get valid results from wbinfo -u or -g. /etc/init.d/winbind restart fixes the problem. I can't find any info in the logs, but I get the following when I restart winbind:

[2004/04/27 08:35:09, 1] nsswitch/winbindd.c:main(843)
  winbindd version 3.0.2a started.

net ads testjoin says OK - is that last message normal?

Here is my testparm output:
