Fwd: Re: Re: High CPU usage on some of the nodes due to message coalesce

Any cron or other scheduler running on those nodes? no Lots of Java processes 
running simultaneously? no, just Apache Cassandra Heavy repair continuously 
running? none Lots of pending compactions? none, the cpu goes to 100% on first 
seconds of insert (write load) so no memtable flushed yet,  Is the number of 
CPU cores the same in all the nodes? yes, 12 Did you try rebooting one of the 
nodes? Yes, cold rebooted all of them once, no luck! Thanks for your time
