Have you got a sniffer to trace the error ?
It would be interesting to see the packet in question
since ICMP has 20 ish different error codes.
The ICMP error should not be broadcast either, it
should be unicast back to the originator of the
erroring device. Off the top of my head I cannot think
RFC 1256 looks interesting.
>>> SNIP
This document specifies an extension of the
Internet Control Message
Protocol (ICMP) to enable hosts attached to
multicast or broadcast
networks to discover the IP addresses of their
neighboring routers.
>>> END SNIP

Hi
is an ICMP response SUPPOSED to go to a broadcast address? I'm probably off
in left field here, but your server should be sending UDP to a directed
broadcast address, shouldn't it?
what does your server / application documentation say?

In general, ICMP messages should go to a unicast address. A device could be
misconfigured with the wrong subnet mask, causing it to send to an address
that it thinks is a unicast but the recip
Check your subnet masks. Your Linux server is sending to a broadcast
address which would indicate that there is a machine configured with the
broadcast address of a subnet - not a host address. And yes - some OSs
allow that.
