[vz-dev] Middleware Absturz

[Roland Kletzing]

> Frage wäre: Was kann ich tun?
Statt 2 Datenbanken evtl. nur eine verwenden? Unnötige Prozesse/Dienste 
abschalten oder ungenutzte Apache-Module entfernen um mehr freien Speicher 
zu bekommen?
Zumindest sieht man daß sowohl postgres als auch mysql Prozesse gekillt 
wurden bzw. einen Kill ausgelöst haben, das erscheint mir seltsam.

Grüsse
Roland
