Build: NetBeans IDE 8.1 (Build 201510222201) VM: Java HotSpot(TM) 64-Bit Server VM, 25.60-b23, Java(TM) SE Runtime Environment, 1.8.0_60-b27 OS: Windows 10 User Comments: GUEST: I guess it was because I opened a 64 MB large text-file (SQL-dump) in NetBeans - did some changes an tried to save them, but this made an exception, then I closed the file and discarded the changes. After this the CPU and memory usage of NetBeans went through the roof :) GUEST: Again, about an hour into work, and Netbeans runs up to ~100% of a I7 with 12G of ram. This time the git repository has been removed from the loaded project, so it's not git related. paulcsf: Netbeans uses ~100% of an I7 with 12G of ram, unresponsive. Usually within an hour of starting. No git repository in project directory. Project directory consists of 2700 files, 247 folders, ~60MB. Mostly PHP and Javascript. GUEST: <5 minutes after restart after the last Netbeans crash, and it's already crashed again. ~100% processor usage, unresponsive.

Reference issue/report 251260, 250620, 256063, 225747. I understand they may be different point to different outcomes, but the behavior, project tree (in my case), system (in my case), are all the same.
