[Samba] High count of smb processes

[Guenther Bergmann]

Hi,
i've got an strange problem here which i can't resolve without any 
help. First of all some information on the network and the 
environment:
We have 8 different locations, consisting of 11 lans (class-C 
subnets with netmask 255.255.255.0). These locations are connected 
via routers. At each location we have 1 to 3 AIX servers running 
samba. AIX is version 4.3.3 with ML 9 or 10. Samba is version 
2.0.7.
Windows NT Networking is working fine; each of the locations 
constitutes one NT 4 domain.
The samba servers all belong to one Workgroup (called "workgroup").

The problem is: we see Samba servers which spawn a lot of smb 
processes. The count goes up to about 300 processes without one 
share being used. Applications supporters are not really happy with 
this count of smb processes because they see a significant 
performance degration. Btw: Clients can connect fine.

I have found the following information in the logfiles:

2003/01/22 17:32:25, 2] smbd/reply.c:reply_special(97)

I am especially wondering about the the 
 open_oplock ipc: pid = 96100, global_oplock_port = 3671
line. I have situations where this messages occurs every 2-3 second.

If it ist of any help i can post smb.conf as well.

Can anybody shade a light on this ?

best regards

Guenther
