Sometimes one of the 4 tcpdump processes does= n't capture a packet and doesn't write it to file. I have added ktrace to see what's going on. The result is really surprising to me: 4795 tcpdump 0.026949729 CALL cap_enter 4795 tcpdump 0.026952795 RET cap_enter 0 4795 tcpdump 0.026955109 CALL read(0x3,0x2ffc0362a980,0x80000) 4795 tcpdump 0.054705876 RET read RESTART 4795 tcpdump 0.054708762 PSIG SIGKILL SIG_DFL code=3DSI_NOINFO Something immediately kills one of the tcpdumps. Digging further. --=20 You are receiving this mail because: You are on the CC list for the bug.=
