16.04 - phpstorm and new ubuntu/java update overheating - Ask Ubuntu

3 days ago updated ubuntu , restarted.

my java process, launch phpstorm, go 600% cpu usage , kills pc in 20 second.

i on phpstorm 8 java openjdk 8.

as test tried swap oracle version same result!

then manually removed phpstorm system , updated last version, 10th.

still overheating no chance work on it! suggestion?

my system is:

edit comments: still following error:

this should not possible provide system maintained. i7-2630qm cpu has thermal monitoring technologies. being case, if cpu overheating (max temp 100c) cpu must faulty it's designed downclock , continue working if gets hot.

thermal monitoring technologies protect processor package , system thermal failure through several thermal management features. on-die digital thermal sensor (dts) detects core's temperature, , thermal management features reduce package power consumption , thereby temperature when required in order remain within normal operating limits

edit:

since using intel_pstate driver , doesn't appear working you try disabling , using acpi frequency control instead described in this answer. install indicator-cpufreq package , adjust clock rates manually. note changing acpi frequency control typically provide more choices indicator-cpufreq intel-pstate driver.

if system isn't maintained, packed dust, cooling fan may failing or have failed. (none of work when can't breathe.) if problem you'll find options here
