I've been seeing something kind of odd behavior from of my elementary OS install:
When I left the machine running as a guest on my VMWare ESXi server overnight, it would plateau in CPU use once every ten minutes or so. Other VMs, like Windows 7 and Ubuntu 14 will typically max out at like 0.2 GHz when idle, but Gala seems to be pushing this elementary OS install to five times that amount periodically.
Any ideas what could cause this? The big leap in use on the right hand side is when I logged in and after ten minutes ran
gala --replace & to reset Gala, which had consumed like 40 minutes of CPU time in the past day of being idle with no applications running. Another ten minutes after restarting Gala and it's running smooth and clear at under 1% total system CPU-use.
Should I use crontab to force-reset Gala every time I go idle? Anyone have some ideas what might cause this? I've had problems in the past with high idle-CPU use on elementary OS installs (sitting at 1+GHz when not in use), but this is the first time it made a time-variable pattern like the above screenshot.
