             Summary: NetBeans 11 unbearbly slow due to infinite scanning of 
projectsa
                 Key: NETBEANS-2671
                 URL: https://issues.apache.org/jira/browse/NETBEANS-2671
             Project: NetBeans
          Issue Type: Bug
    Affects Versions: 11.0
         Environment: Windows 10 64
            Reporter: Grzegorz


As netbeans is best program ever to edit PHP code for me, it has one flaw since 
8.0. It can sometimes hang on background scanning without any reason.

What I tried: 
- Restart
- Cache Clear
- Project delete and create new one
- Also Disabled: Menu -> Tools -> Options -> Miscellaneus -> Files -> Enable 
auto-scanning

Problem occurs on every start of netbeans with startup scan.

Cannot cancel scan.
Added not needed dirs into ignore folders.

 

Below is exception from log.
