Hi,
I recently upgraded from 13-STABLE to MAIN, now at FreeBSD 14.0-ALPHA1 amd64
1400094 #12 main-n264689-580cadd6a5f0, a custom kernel compiled *without* IPv6
(WITHOUT_INET6=yes).
Ever since either upgrading to MAIN or WITHOUT_INET6=yes [1] I noticed that
periodic daily still runs in the morning failing to mail ridiculously huge
report files (>= 90 *GB*).
[1] Can't remember when this started.
I believe to have found the step in periodic daily causing these huge files,
but I do not know why:
1) I used to run default daily_status_network_netstat_flags="-d -W" in
/etc/periodic.conf
This normally produces an output like:
MWN> netstat -i -d -W -n

But pretty often "netstat -i -d -W -n" produces garbage like spaces or "0".
This fills /tmp pretty fast (luckily a compressed zfs filesystem) and my mta
still tries to mail in the morning.
2) I modified /etc/periodic.conf to daily_status_network_netstat_flags="-d -W
-4"
This produces an output like:
MWN> netstat -i -d -W -n -4

This fixed my issue with periodic daily.
But I would like to know, if this has to do with WITHOUT_INET6=yes or FreeBSD
14?
Or something different ...
Did someone of you experiences equal behaviour of "netstat -i -d -W"?
Anyone with WITHOUT_INET6=yes willing to test this?
Regards,
Michael
