Hello,
I have a Debian machine with samba 3.0.2a-1 (which should bei identical
to samba-latests, AFAIK). For a reason not yet known nmbd processes keep
hanging around forever, eating up memory slowly, but steadily.
Logfiles do not show anything suspicious (to me, at least, I don't want
to put a days level 10 log in here), except from things like
| Mar 8 10:06:22 bertha kernel: Out of Memory: Killed process 30214 (nmbd).
when finally running out of memory. For a hanging process, lsof is showing the
following (skipping dynamic libraries):

An strace results in:
| recv(1076380172,
And waiting there forever.
Is there anything I can do to help hunting down the problem? And is there
anything I can do _now_ to prevent it? A daily "killall -9" does not
seem
to be a nice solution to me.
Bye,
Stefan
