Do you have a copy of the actual script that you are using?

Trying the following on try.bro.org with exercise_traffic.pcap seems to
work fine:


redef udp_content_deliver_all_orig=T;
redef udp_content_deliver_all_resp=T;

event udp_contents(u: connection, is_orig: bool, contents: string) {
	print contents;
