Some of these post remind me of the Irish joke with one engine after another giving up and the flight time ever increasing and one pax saying if this keeps going on we'll be up here all night.
It does not matter how good the aircraft is and how it's performance is affected with one engine out.
If the same problem is continuing and it has happened again to one engine it can happen to the others and if that's not a safety issue I don't know
what is.
