Wir hatten gerade einen Vorfall auf einem unserer Webserver. Mehrere PHP-Anwendungen werden darauf ausgeführt und haben die folgende Fehlermeldung ausgegeben:
php_network_getaddresses: getaddrinfo failed: Name or service not known
Diese Nachricht scheint netzwerk- / DNS-bezogen zu sein. Aus den Serverprotokollen ging eindeutig hervor, dass Ubuntu zu dem Zeitpunkt, als der erste Fehler auftrat, eine unattended-upgrades
Sitzung startete . Ich werde die Ausgabe von dpkg.log
unten anhängen .
Wir verwenden einen externen Datenbankserver.
Wir haben beschlossen, den Webserver neu zu starten, wodurch das Problem behoben wurde. Die Frage lautet nun:
Gibt es eine Möglichkeit, die zugrunde liegende Ursache dieses Problems herauszufinden, damit ich es in Zukunft verhindern kann?

Antworten:
Wir haben gesehen, dass dies unsere Umwelt getroffen hat und es ist 5 Stunden später wieder passiert. Erwägen Sie ein Rollback auf eine ältere Version des libc6-Patches.
Hier ist der Ubuntu-Fehler für dieses Problem, der bestätigt, was wir alle sehen: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/1674532
Update: Das Problem wurde inzwischen behoben.
Siehe Kommentare Nr. 16 , Nr. 17 und Nr. 18 im obigen Bericht. Das Aktualisieren
libc
sollte das Problem beheben. Ein Neustart wird empfohlen, um sicherzustellen, dass alle laufenden Prozesse, die während des Updates ausgeführt werden und diese Bibliothek verwenden, weiterhin ordnungsgemäß funktionieren.quelle
