samba - Apr 1999 - Samba eating CPU ressources

Since we upgraded from 1.9.18 to 2.0.3 Samba processes (smbd) are
"eating" sometimes 40-45% of the cpu time for ONE process !!!. Before
it
was never greater than 3 - 5% for each smbd. We use Sun e450 with Sol
2.5.1, gnu 2.7.2 and nearly 60 NT-ws clients with sp3 or sp4. Especially
when people are working with netscape (netscape cache is in their
homes), but also with some other application (SPSS). We plan to set for
all 2000 users netscape cache on c:\temp, but with 1.9.18 this problem
was not existing. I used also my compiled samba and binary from samba
site, the same effect. my smb.conf:

# Samba config file created using SWAT
  # from 
  # Date: 1999/04/14 15:22:53

  # Global parameters
          workgroup = WIWI
          security = SHARE
          log file = /usr/local/samba/var/log.%m
          max log size = 500
          time server = Yes
          socket options = TCP_NODELAY
          load printers = No
          domain logons = Yes
          os level = 65
          preferred master = Yes
          domain master = Yes
          wins proxy = Yes
          wins support = Yes
          dos filetimes = Yes
          dos filetime resolution = Yes
          fake directory create times = Yes

  [homes]
          comment = Homes
          read only = No
          create mask = 0750
          browseable = No
          oplocks = No

  [apps]
          comment = APPS
          path = /export/win/apps
          write list = ntadmin
          read only = No
          create mask = 0775
          guest ok = Yes

  [public]
          comment = PUBLIC
          path = /export/home2/public
          write list = ntadmin, @mit, @vw
          read only = No
          create mask = 0775
          guest ok = Yes

  [install]
          comment = INSTALL
          path = /export/win/install
          write list = ntadmin
          read only = No
          create mask = 0775
          browseable = No


I have oplocks = no on homes, because for some reason working with
Visual Basic on homes with oplocks was not possible.

Any ideas ?

I have always had this problem with netscape.  Always 
better to cache to the local disk.  Wish I had more 
information for you.

I would suggest doing a combination of truss and using 
smbstatus to see what is going on though.





Cheers,
