Konstante TCP-Anforderungen und fehlgeschlagene Antworten

Ich bekomme pro Sekunde eine davon:

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 

Jedes Mal, wenn der Quellport um 1 erhöht wird, ist das Ziel immer 23454

Ich habe jede App geschlossen, WLAN deaktiviert, keine Ethernet-Verbindung hergestellt und versucht, den Prozess im Anwendungsmonitor zu schließen, der Netzwerkverkehr hatte.

Jede Hilfe wäre dankbar
