[Snort-users] need help : (snort decoder) Bad Traffic Loopback IP

Hello,
i'm running 3 snort (2.4.3) sensors logging to one db.
All systems run suse 9.2 and have very similar setups.
Snort Setup and installation is exact identical.

On one machine i get a
(snort decoder) Bad Traffic Loopback IP
with
127.0.0.1:2638 255.255.255.255:2638 UDP
report.
How can i trace where this broadcast came from (pid)/PC ?
I wonder why only one pc gets this broadcast msg, for testing i pulled
this pc out of network and msg didn't come again.
Now i wonder if it is generated by the pc itself - but why vanished msg
when pulling off network cable- or if msg comes from network - but why
don't fetch other sensors this msg - .

i don't wanna disable complete decoder to get rid of this message. But
in the end i'd like to find out what src of msg is and stop it.
