the smbd grped form ps output is at 60% for about 12 houres. on this 
machine one process like these is no real harm as it's a dual xeon.

yes, and these kind of proces are still there when i stop samba with the 
initscript. i've to kill -9 them. i also can kill them while samba is 
running. this is no harm to the system at all. i've no compalins when i do 
this.

> Do you have any log files?

yes, but at the current loglevel i've only a fewl lines about the ldap 
connections. i can increase the loglevel. but it will be hard to monitor 
the system in a way, that allows me to get the exact point of time when one 
process is running wild. so it will be hard to find a corelation of 
logmessages an this point of time. but i will do my very best.

cheers
matthias
