I'm pretty sure you will only see "LISTEN" for TCP ports not UDP.

$ lsof -i tcp:657
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
rmcd 331940 root 14u IPv4 0xf1000600020a7b98 0t0 TCP *:rmc
(LISTEN)

$ lsof -i udp:657
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
rmcd 331940 root 3u IPv4 0xf1000600020b4000 0t0 UDP *:rmc

"lsof -i tcp:657" retuns nothing.

lsof -i udp:657
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
rmcd 1147036 root 3u IPv6 0xf100020003f7bc00 0t0 UDP
*:rmc

Have you tried,

# stopsrc -s ctrmc
# startsrc -s ctrmc
