Because... 😄

Probably they are unhappy about something? My very first guess would be to look at logs...

Yeah, they are unhappy... but they don't tell what they want...  
i have observed that after 5 days, they fail... do they get tired.

When i delete the indices, it works. But that's not a solution

I am interested to diagnose them. how can i check whats wrong.  
I tried all the CAT command, everything looks green and happening... but shards are failing. ☹

If they are failing you probably have a trace in logs.
