I have 9.1-STABLE r253105 system, which started to flood logs with "sonewconn: pcb 0xfffffe0053916dc8: Listen queue overflow: 193 already in queue awaiting acceptance" messages (there are thousnds of it, if you take "last message was repeated 600 times" in account). Nothing was changed in settings for long time. How could I determine, which connections (listen port, at least) cause these messages? -- // Black Lion AKA Lev Serebryakov
