Martin Joyce commented on NETBEANS-2940:
----------------------------------------
I'm just lost with this issue. The heading refers to cpu usage "during HTML/PHP
project parsing". Well, I've certainly got HTML and PHP on the workbench and
for sure I've got excessive cpu use. My laptop has literally fried my kneecaps!
Whether parsing is the issue I know not. All I know is that if I open an html
file and so much as hit the space bar (ie make a minor correction), the cpu
climbs over 30%. This has killed my PC and must be going some way to killing
the planet as well!
I'm on Apache NetBeans IDE 12.1 now, having migrated from Netbeans 8.1, hoping
to fix this. I've got the new "Pause I/o checks" button and have unset "Enable
auto-scan of sources" but still my kneecaps fry.
The issue is stated as "resolved"/"abandoned". So, just to be clear - is there
no fix to my problem?

> Very often Netbeans would start consuming high CPU resources for the job of
> Checking for external changes, which sits in suspended status. If you click
> on the cross and manually cancel that job, the CPU will keep being consumed.
> The only way to stop this is to completely close Netbeans. Upon closing, it
> will say that it is still checking for external changes.
