Hello,

since we patched our RAC system last weekend CloudControl monitors on both hosts a peridodicaly (once per hour) "i/o boost"  one system 300  the Other system over 900 million i/o. See the screenshot.

I checked jobs, crontab, database activity and found no hints what is causing this.

Thinking about the server performance (6 Year old x86, two 8-Core CPU Xeon E5640 Core 2 Port-8GBit SAN) the values are also far beyond any reality.

Is this a bug?

Does anybody have a idea what is causing this behavior?

Some more systeminformations:

uname -a : Linux xxxMYHOSTxxx  4.1.12-112.14.13.el7uek.x86_64 #2 SMP Thu Jan 18 11:38:29 PST 2018 x86_64 x86_64 x86_64 GNU/Linux

Howdy, Stranger!
