System was running a composer ( plasma5 ) with compositor using in OpenGL 3.1, GLX interface. Behavior was replicated as well with compositor using OpenGL 2.0 GLX interface. Only using Xrender ( raster ) compositor system becomes stable. Before the freeze period, system experience faster cpu usage, reach 100% previous freeze and crash. All system functions becomes freeze for some time, restoring itself later.
Same error today... and I confirm the Helio's described behaviour.
