Default Kernel Bug zabbix-proxy

Hallo,

seit einiger Zeit haben wir Probleme mit unseren Daensammeln in den RZ.
Es sind kleine Linux-Arm-Proxys mit einem Debian 7 und Zabbix-Proxy 2.4

Uns ist bewusst das dies nicht den aktuellsten Stand representiert, aber wir vermuten nicht das dies das Problem des Kernelbugs dastellt.
Hier der Kernel Bug:
Code:
Debian GNU/Linux 7

Der Server ist noch 2.4.8. Der Zabbix-Proxy ist 2.4.7

Was wäre hier die beste vorgehnsweise. Alles auf 2.4.8 zu bringen oder direkt sehr viel arbeit und alles auf eine 3.X version? Oder auf eine neue LTS warten?
Derzeit ist so das die Proxys mal Monate laufen und dann nur Tage. Ein Reset lässt diese wieder laufen aber das ist ja keine Lösung für eine Überwachung.

Über eine Einschätzung und Lösungansätze wäre ich sehr dankbar!

beste Grüße
