I have noticed a OS error in my diag log and i also notice that HADR is not in sync during this period.
From error message, I am not completely clear which resource is unavailable ?
I suspect that Network is not good during that time.
Will there be chance for any other resources?
How to dig it further?
Its an AIX machine.
Below is the DIAG log piece.
