Thumbnails generieren Fehler

Hallo zusammen,

habe nun per SSH die Thumbnails neu generieren lassen. Leider hat er diesen Prozess abgebrochen. Wie viele Bilder er genau schon neu generiert hat weiß ich nicht, jedenfalls war der letzte stand zuvor bei gut 8000 Bildern. 116000 sind es insgesamt.

 

Genutzt habe ich diesen Befehl: 

 php bin/console sw:thumbnail:generate -f

 

Fehlermeldung:

An exception occurred while executing 'SELECT
  ce.name,
  COALESCE(currentShop.value, parentShop.value, fallbackShop.value, ce.value) as value

Was könnte der Fehler sein?

Keiner eine Idee?

“MySQL server has gone away” = zu schwaches Hosting.

Welche Parameter muss ich da hochdrehen? Zu Schwach ist das sicher nicht.  

Tippe ich die Zeile „MySQL server has gone away” mal bei Google ein oder noch besser schicke sie an deinen Hoster.
