Hallo,

ich habe das Problem, dass mir ab und zu das Control-Panel mit einem "Service Unavailable" und einem Segfault-Error in den Logs wegfliegt.

Server: Debian 9.9
Keyhelp 9.1 (ich habe das Update noch nicht manuell angestoßen)
CPU-Kerne: 4x
RAM: 16 GB
free -m -h

Ändern tut sich nichts. Ein Reboot hilft.

Hat jemand eine Idee, wie ich hier weiter vorgehen kann?

Danke uns beste Grüße, Christian

Stehen im kern.log zum fraglichen Zeitpunkt eventuell noch relevante Infos?

=> REBOOT

Jul 18 11:53:45 mail kernel: [    0.000000] Linux version 4.9.0-7-amd64 (debian-kernel@lists.debian.org) (gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1) ) #1 SMP Debian 4.9.110-3+deb9u2 (2018-08-13)
Als Hinweis noch:
das ganze läuft in einer XEN-virtualiserten VM mit LVM und ext4 Dateisystem.
XEN / LVM habe bisher mit Confixx / Plesk insgesamt über 10 Jahre ohne Probleme betrieben...

Ich bin hier allerdings gerade etwas ratlos.

Hmm...Sagt auch nicht mehr aus.
Hast du schon mal das Loglevel für PHP hochgesetzt (error_reporting = E_ALL)?

Hallo,

nein noch nicht.
Es ist auch nur PHP 7.0 und ein zwei Benutzer mit den PHP7.0-Versionen betroffen.
Benutzer mit 7.2 oder 5.6 laufen weiterhin....

Ich werde da die Log-Level nochmal hochsetzen und weiter die Augen und Ohren offen halten und googlen.
Falls jemand Tips hat, ich wäre sehr dankbar!

Christian

Ich hatte so ein ähnliches Verhalten vor längerer Zeit auch einmal. In dem Fall war der PHP-Interpreter Amok gelaufen, weil ein Script massig deprecated-Warnungen generiert und so den Interpreter in die Knie gezwungen hatte (nur so als möglichen Hinweis bei deiner Fehlersuche).
