[Samba] High Load on Reliant Unix 5.45A20

[sascha.laatsch at lva-rheinprovinz.de]

Hello there!

We have a Performance-Problem on our Fileserver!

Hardware: RM600 E70
           12x R10000 CPU
                      8 GB RAM

OS: Reliant Unix 5.45A20
Samba-Version: 1.9.18p10
Number of Samba-Processes: ca. 2800


By Time the Number of blocked Processes is more than 600 but our CPU-Idle
is higher than 50%.

Siemens tells us that in this Situation the Value  "pswitch/s" (checked
with"sar -w") is at  9000 an this is definitly too much for the System
(Normalvalue 1000).
This may me the Reason for the high Load and Number of blocked Processes.

Does anyone know this problem and is there a solution for it  ( eg. in
smb.conf tuning or source-code)
