The other day, I explained about a condition, more than one hundred alerts were blinking and nobody could not understand what the system happened.

It is called "Christmas tree (alert avalanche)”.

I thought that only enormous systems like nuclear power plants that need a central control room, become to cause such tragedies.

Few days ago, when my wife used a washing machine in my house, she called me and said

"All indicators of the washing machine because to be blinking suddenly"

Ebata:"Does the system work well?"

Wife:"The system?"

Ebata:"Washing machine"

Wife:"Yes. It works well"

Ebata:"O.K. Keep it without doing anything by the end of the washing program."

Wife:"Can I leave it alone? They are blinking now"

Ebata:"No problem"

”At least, our washing machine does not "meltdown" at its worst.”
