Kernel messages when running elasticsearch


(calc) #1

Hi there, ever since I started running ES on one of our machines, I'm
seeing the following kernel messages quite often. Then I started a second
machine running as full replica of the first machine (all indexing requests
are still sent to the first machine, averages between 10-20 documents per
second), but I don't see such kernel messages at all on the second machine,
and the first machine is still having these kernel messages. Are these
messages alarming? Or can I just ignore it?
