Thank your for your explanation. Matthew Seaman [2016-03-29 13:05 +0100] : > Looks like the obhttpd process is trying to kill of its children > individually, but they've all already been killed.

So there's nothing to worry about too. Nonetheless, I'm wondering: After more than three hours, the output is still the same? I just started www/obhttpd again and got the following: USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS www obhttpd 9308 4 tcp4 10.15.1.1:80 *:* www obhttpd 9307 4 tcp4 10.15.1.1:80 *:* www obhttpd 9305 4 tcp4 10.15.1.1:80 *:* root syslogd 4654 6 udp6 2a00:c98:2200:af07:6:0:1:1:514 *:* root syslogd 4654 7 udp4 10.15.1.1:514 *:* ? ? ? ? tcp6 2a00:c98:2200:af07:6:0:1:1:80 *:* ? ? ? ? tcp4 10.15.1.1:80 *:* ? ? ? ? tcp6 2a00:c98:2200:af07:6:0:1:1:80 *:* So it seems that www/obhttpd has problems binding again on IPv6 while IPv4 works fine. Stopping and starting again gives me an additional "closed" port on IPv6: USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS www obhttpd 9355 4 tcp4 10.15.1.1:80 *:* www obhttpd 9354 4 tcp4 10.15.1.1:80 *:* www obhttpd 9352 4 tcp4 10.15.1.1:80 *:* root syslogd 4654 6 udp6 2a00:c98:2200:af07:6:0:1:1:514 *:* root syslogd 4654 7 udp4 10.15.1.1:514 *:* ? ? ? ? tcp6 2a00:c98:2200:af07:6:0:1:1:80 *:* ? ? ? ? tcp6 2a00:c98:2200:af07:6:0:1:1:80 *:* ? ? ? ? tcp4 10.15.1.1:80 *:* ? ? ? ? tcp6 2a00:c98:2200:af07:6:0:1:1:80 *:* Something's not working properly here, is it?
