Preclear Post-Read=High CPU usage

Featured Replies

Hello all,

 

Like the title says I was trying to figure out what was using nearly 50% of my 40 CPU cores, maxing out half of them for 10 mins at a time and then 3 mins of calm before the cycle starts again. I thought it was my dockers so I powered off the ones I thought would be causing this and there was no change. I powered off all of the dockers and still the issue persisted. I checked TOP and the highest CPU processes were DD and CMP... thus I stopped the post read process and everything returned to normal... 

 

Is this something that others have encountered?

I will note that during the high cpu windows, nearly everything froze while that was going on... dockers were unresponsive and it was just weird...

This isnt the first time that I have had this happen... 

 

I would agree with you... but if it was a disk problem... Why would the CPU spike on a post read operation?
