Getting Data In

UDP and the 1472 bytes limit

We are receiving syslog data via UDP and we noticed that some data is missing.

When running - 

tcpdump -i eth0 port <udp port>

I see lines such as - 

UDP, bad length 5158 > 1472


And the data is not being ingested. 

https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fnetworkengineering.stackexchange.c...   says - 

The 1472 is the maximum payload length for the UDP datagram.

Any ideas how to deal with it?
