[Samba] Sambaserver slows down, too many smbd processes

Hi folks,

maybe my problem was discussed before, but I'm just too busy to browse
the whole mailinglist at the moment.

I'm running Samba 3.0.14a(sernet) on a Debian Sarge with LDAP-Backend.
After some days, the users aren't able to load their profiles from the
server. In fact, no datas can be transfered from/to the sambaserver.

The cpu load is nearly 50 percent (it's a Pentium 3,0GHz, 2GB RAM with
only 10 users). A "ps aux" shows about 30 smbd-processes. When I try to
stop samba via "/etc/init.d/samba stop", this doesn't affect the
processes. Only "killall -9 smbd" helps. After restarting smbd/nmbd
everything works fine again.

Following entries attract my attention:

/var/log/syslog:

Maybe that's normal, maybe not.

And maybe anyone out there had similar problems before and can help me.

Thanks
Holger
