Closed NB and reopened it.
Was fast until 93% then background scanning went back to 0 and got stuck at 5%.

I have to switch back to previous build, sorry.

Seems to me it is a P1.
Comment 3 aquaglia 2014-02-24 09:40:56 UTC 
With the following build it works fine:

Assigned more memory but it gets stuck anyway:

Comment 5 Tomas Hurka 2014-02-24 09:54:24 UTC 
Can you, please, attach messages.log and selfsamler.npss http://wiki.netbeans.org/FitnessViaPartnership . Reassigning to editor/parsing for further evaluation.
Comment 6 Tomas Zezula 2014-02-24 09:56:37 UTC 
In the thread dump there is no blocked thread.
Please attach selfsamler.npss when the scanning is frozen.
Thanks
Comment 8 Tomas Zezula 2014-02-25 10:16:51 UTC 
Thanks for snapshots: there are javascript, html, css indexing.
Namely:
Snapshot1 and Snapshot2 - most Html + CSS
Snapshot3 - mostly JS.
Comment 9 aquaglia 2014-03-11 09:52:03 UTC 
I have just installed NB 8.0 FCS and I am encountering the same problem.
