Hi list!

We have a problem with our samba server (version
3.0.14a-1 running on SuSE Enterprise OS). After some
time of inactivity (about 15 min) the clients get some
delay when they reconnect to a share. When the want to
open a document it takes about 5-10 secs until it
opens. After first reconnect everything work fine.

Which parameter could i change to fix this problem?
I already tried deadtime, keepalive, SO_KEEPALIVE and
serval other. 

Server hardware: Intel Xeon 2,8 GHz, 2,5 GB RAM, 2
giga nics and SAN hdd.

server:~ # hdparm -Tt /dev/sdb

/dev/sdb:
 Timing buffer-cache reads:   128 MB in  0.20 seconds
=640.00 MB/sec
 Timing buffered disk reads:  64 MB in  0.78 seconds =
82.05 MB/sec
 
Here is my config.

[global]
        workgroup = test
        netbios name = server
#       server string = server
        name resolve order = wins host bcast
        socket options = TCP_NODELAY IPTOS_LOWDELAY
SO_SNDBUF=8192 SO_RCVBUF=8192 SO_KEEPALIVE
        interfaces = eth0 eth1
        wins support = yes

        load printers = no
        show add printer wizard = no

        case sensitive = no
        max xmit = 8192
        getwd cache = yes
        oplocks = yes
        keepalive = 120

        os level = 64
        preferred master = yes
        local master = yes
        domain master = yes
        domain logons = yes
        admin users = @administrator

        security = user
        encrypt passwords = yes
        log file = /var/log/samba/log.%m
        log level = 3
        max log size = 5000
        hosts allow = 127.0.0.1
xxx.xxx.xxx.xxx/255.255.255.0

        unix password sync = yes
        passwd program = /usr/bin/passwd %u
        smbpasswd file = /etc/samba/smbpasswd
        passwd chat = *New*password* %n\n
*Re-enter*new*password* %n\n *Password*changed*

        logon drive = I:
        #logon path = \\%N\profiles\%U
        logon script = %U.bat

Heres the part of the config:
