== (not perfect) Coincidence between sudden increase of CPU load and ETMY glitch ==
[Miyakawa, Yamamoto, Enomoto]
As Miyakawa-san suggested, we looked at CPU meter and ETMY oplev output.
Please find the attached figure.
At first glance it seemed they show perfect coherence, but, looking carefully, you can find a few examples where only the glitch happened but CPU increase did not, and vice versa.
Need to continue investigating.
