Bug 267348

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: Linux

User Comments:
GUEST: The process of looking for external changes kept being suspended

GUEST: building vagrant boxes

GUEST: Hung for a while on "Background scanning of projects", and then continued to use a huge of amount of the CPUs.

Willynux: Was trying to import project from someone else

GUEST: This seems to happen when I switch away from Netbeans for a while. Note that I have the manual scan plugin because background scanning was always making Netbeans way too slow.

I usually have one or more PHP projects with quite a lot of files (Drupal installations).

GUEST: OutOfMemoryError: Java heap space

GUEST: Froze on me when I tried to debug

GUEST: when I open every time this message is showing I reinstalled the netbeans still same issue

GUEST: Please provide a description of the problem or the steps to reproduce

GUEST: Background scanning issue, had caused processor to max out, had to force exit.

GUEST: <app crach>

GUEST: nothing
