After the message, the machine becomes completely unresponsive and I have to do a power-off, power-on reset.

Is this something I should be
worried about, or is it indicative of something else faulty in the local
network setup?
This message is produced if the ethernet card receives a packet that is bigger than permitted by the MTU + the size of the ethernet header. For normal ethernet this means that packets should be <= 1514 bytes.
So, there are three ways to eliminate the the message:
1) Find the machine sending oversize packets and stop it. 2) Change the MTU on your interface using ifconfig, this will only work if the other machines on the network expect larget frames. 3) You could edit /usr/src/sys/net/if_ethersubr.c and remove the code that prints this error and then recompile your kernel.
