Package: ntp
Version: 1:4.2.4p4+dfsg-8lenny3
Severity: critical
Justification: breaks the whole system
Hi There,
We've just had an issue were a server became unresponsive after NTP started
switching status as per the daemon log below:
Oct 13 19:15:44 mb ntpd[1966]: kernel time sync status change 4001
Oct 13 20:06:59 mb ntpd[1966]: kernel time sync status change 0001
Oct 13 20:41:09 mb ntpd[1966]: kernel time sync status change 4001
Oct 13 20:58:14 mb ntpd[1966]: kernel time sync status change 0001

Oct 13 21:43:43 mb afpd[5409]: Connection terminated
Oct 13 21:43:43 mb afpd[2052]: server_child[1] 5409 exited 1
Oct 13 21:49:26 mb ntpd[1966]: kernel time sync status change 4001
Oct 13 22:06:30 mb ntpd[1966]: kernel time sync status change 0001

Oct 14 00:57:16 mb ntpd[1966]: kernel time sync status change 4001
Oct 14 01:48:31 mb ntpd[1966]: kernel time sync status change 0001
Oct 14 02:56:49 mb ntpd[1966]: kernel time sync status change 4001
Oct 14 03:48:02 mb ntpd[1966]: kernel time sync status change 0001
Oct 14 06:38:45 mb ntpd[1966]: kernel time sync status change 4001
Oct 14 08:21:13 mb ntpd[1966]: kernel time sync status change 0001
Oct 14 09:46:37 mb ntpd[1966]: kernel time sync status change 4001
Oct 14 10:03:40 mb ntpd[1966]: kernel time sync status change 0001
Once the server was rebooted, netatalk (afpd) clients could reconnect again.
and SSH connections once again worked.
I'm not 100% sure that NTP caused the issue, as the status changes have been
reported previously without causing unresponsiveness. However there is no other
logs indicating any other failures.
Regards,
Mark
