[j-nsp] Syslog getting spammed by DDOS_PROTOCOL_VIOLATION_SET

[Karl Gerhard]

Hello

our syslog is getting spammed with the following messages:
jddosd[12168]: %DAEMON-4-DDOS_PROTOCOL_VIOLATION_SET: Protocol resolve:ucast-v4 is violated at fpc 11 for 1389 times
jddosd[12168]: %DAEMON-4-DDOS_PROTOCOL_VIOLATION_CLEAR: Protocol resolve:ucast-v4 has returned to normal. Violated at fpc 11 for 1389 times

What is puzzling is that there is barely any traffic going through that machine (like 5 MBit/s). It seems like those messages are being triggered by random noise from the internet just by announcing a single /18.

Is that normal? Is there a way to gracefully handle those messages (i.e. save them into another file) without losing important information?

Regards
Karl
