What can make the mtu drop on a running system?
The DHCP server (if you are using dhcp).
# Update on 12/13/2007
# -M Prevents dhcpcd from setting the MTU provided by the DHCP

# If this option is not enabled, this occurs:
# p34:/etc/init.d# netstat -i
# Kernel Interface table
#Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg
#eth2 576 0 41603246 0 0 0 21618577 0 0 0 BMRU

^^ Not sure if my explanation is quite right but fixing it so the MTU is not
changed fixed the problem :)
