Mac crashes on SMB activity. Help me

[3mors]

This is my problem:

few days ago, i connected my new dual G4 to the office network in order to share some GBs of stuff, but once a PC started to download files from my mac, the mac crashes (kernel panic).
The network is well setted with static IP. I know that this isn't the problem.
On my mac I have jaguar 10.2.2 and this is my smb.conf file:

[global]
client code page = 437
coding system = utf8
; guest account = unknown
encrypt passwords = yes
netbios name = powerserver
workgroup = hampcake
security = share
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

[homes]
comment = User Home Directories
browseable = no
read only = no
create mode = 0750

[movies]
path = /Volumes/firewire/Movies
public = yes
only guest = yes
writable = yes
printable = no

[extra]
path = /Volumes/extra
public = yes
only guest = yes
writable = yes
printable = no


Could u help me?

Anyone can post a link or few words in order to solve my problem?

Thanks for the patience.
