Bugzilla Bug 122912

I'm using the ebuild for openntpd 3.7_p1 which works quite nicely. But after
running about one day the normal output suddenly changes:

reply from 80.190.252.238: offset -0.028608 delay 0.096864, next query 310s
reply from 212.204.235.154: offset -0.021086 delay 0.113792, next query 314s
sendto: Invalid argument
sendto: Invalid argument
...

It just continues to go on like that and doesn't answer to ntp queries anymore.
(I'm using it as LAN ntpd.)

i switched to chrony in the meantime but gladly trying openntpd again. gimme a
few days.

nope sorry still no good
exactly the same problem

hhm, crazy...

can't think of anything. firewall perhaps? 

running strace for a whole day is not really an option, i guess...

i have openntpd running both on x86 and x86-hardened with 300-600 req/min for
months in a row - no problem here.

> can't think of anything. firewall perhaps?

I guess it's a problem of openntpd, 3.9 shows the same symptoms.  

Norbert Buchmuller reported the same bug in Debian, and also came up with a
patch to work around it.  Please see http://bugs.debian.org/392250 for his
description and a patch.

The patch applies to 3.7_p1 as well.

openntpd-3.9_p1-r1 was committed to the tree which applies the patch from the
debian bug tracker - please test. if nothing shows up i plan on asking for
stable marking on that one in a month or two...

thanks for everybodies input - sorry for taking so long...

Is fixed for a long time now...closing
