It is exactly the problematic connection started by the Java process against the port 5432; look the SYN pkg: 19:54:02.940205 IP 10.23.33.19.48438 > 10.23.33.19.5432: Flags [S], seq 3950072774, win 43690, options [mss 65495,sackOK,TS val 3334863612 ecr 0,nop,wscale 7], length 0 As you say, that this is not any Postgres-protocol exchange, I will check the configuration of this part of our software. It can be some kind of misconfiguration, some part is talking TCP/IP to the wrong server.
