[pkg-ntp-maintainers] Bug#802768: ntpd crashes at start up with "Out of Memory" emergency syslog message

[Aleksi Suhonen]

Package: ntp
Version: 1:4.2.8p4+dfsg-1
Severity: important

Dear Maintainer,

    * What led up to the situation?

Upgraded package from 1:4.2.8p3+dfsg-1 to 1:4.2.8p4+dfsg-1 on
a couple of machines.  Now the daemon won't start. Syslog shows this:

Oct 22 14:43:24 humma ntpd[903]: proto: precision = 0.628 usec (-21)
Oct 22 14:43:24 humma ntpd[903]: Listen and drop on 0 v6wildcard [::]:123
Oct 22 14:43:24 humma ntpd[903]: Listen and drop on 1 v4wildcard 0.0.0.0:123
Oct 22 14:43:24 humma ntpd[903]: Listen normally on 2 lo 127.0.0.1:123
Oct 22 14:43:24 humma ntpd[903]: Listen normally on 3 lo [::1]:123
Oct 22 14:43:24 humma ntpd[903]: Listening on routing socket on fd #20 
for interface updates
Oct 22 14:43:24 humma ntpd[903]: Unable to listen for broadcasts, no 
broadcast interfaces available

Kern.log shows this:

Oct 22 14:43:24 humma t of memory [903]

And all interactive terminals show the full "Out of memory [<pid>]" message.
