Hi Edmundo, here is the situation:
we have a PDC and BDC running samba 3.0.23d
we have a Application Server running samba 3.0.24 + winbind.
all have fixed (static) IP addresses in the 192.168.2.X segment. (no
dhcp or whatever)
with resetting, i ment a restart of the samba processes (sorry i was a
little un clear)
some time's i need to remove the .tdb files (except the secrets.tdb)
what i noticed is that the crash/bug happens at peak hour (150 pc's and
so either samba has too many connections (??) or some other process
can't handle it
(i was thinking of the mysql deamon, but he has max connections set to
1000, so that should be enough)
might be the fedora core too ??
so back to testing, i hope the winbind server will keep up today..
btw, no caching name server runnig in the domain...
Cheers, and thx for da input.
