"-s 1472 -M do" is what you would use for this test. Instead, you are sending ICMP requests at 1528 Bytes MTU without DF bit, so it will get fragmented. Anyway, its unlikely that this is the problem. > this is my dump (tcpdump -X) (the message is truncated and I don't > see other packets flowing). Ok, can you confirm that haproxy has been reloaded/restartet after adding the "len" keyword to your logging configuration? > With the logger utility this line gets splitted into multiple packets I'm not familiar with this utility. Can you elaborate whether this SENDS packets to your syslog-ng or if it recieves logs from haproxy? Iirc, a syslog message must fit into a single packet. Regards, Lukas
