The server is an IBM x3650 with 24Gb Ram, with 12 domU (2 paravirtualizzed and 10 fully virtualized), the guest system fully virtualized are FreeBSD 7.1 and 6.4 and there are 10 xenbrX on multiple vlan with a lot of network  traffic...
Sometime the server stops responding (freeze) and on console I haven't any messages for troubleshooting  ...I must reboot...and aren't any log messsage ...:( ..

This problem has occurred since I installed two domU (freebsd) that have lot a network load and CPU...
this is my .cfg template..

######host.cfg#######
#os: FreeBSD 6.4
name = "host1"
builder = "hvm"
maxmem = "4000"
memory = "1500"
disk = [ 'phy:/dev/VG01/LV_host1,xvda,w' ]
vif = [ 'type=ioemu,bridge=xenbr241', 'type=ioemu,bridge=xenbr242' ]
device_model = "/usr/lib/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
sdl=1
vnc=1
pae=0
boot="cd"
vcpus=4
acpi="0"
keymap='it'
######host.cfg#######

sorry for my english...
