Solicitações TCP constantes e respostas com falha

1

Estou recebendo um desses por segundo:

457 205.494657  127.0.0.1   127.0.0.1   TCP 68  49507→23454 [SYN] Seq=0 Win=65535 Len=0 MSS=16344 WS=32 TSval=630136859 TSecr=0 SACK_PERM=1

458 205.494702  127.0.0.1   127.0.0.1   TCP 44  23454→49507 [RST, ACK] Seq=1 Ack=1 Win=0 Len=0

Cada vez que a porta de origem é incrementada em 1 e o destino é sempre 23454

Fechei todos os aplicativos, desliguei o Wi-Fi, não conectei ethernet e tentei fechar qualquer processo no monitor do aplicativo que tivesse tráfego de rede.

Qualquer ajuda seria apreciada
