Description xenoterracide 2014-04-30 16:41:39 UTC

Product Version = NetBeans IDE 8.0 (Build 201403101706)
Operating System = Mac OS X version 10.9.2 running on x86_64
Java; VM; Vendor = 1.8.0_05
Runtime = Java HotSpot(TM) 64-Bit Server VM 25.5-b02


I'm not really sure where to begin with this, or what info might be needed, but memory usage statusline reports 420MB on the heap, max memory 910MB,  actiivity monitory reports process is using 3.43, on startup 1G is pretty common and seems about right, but over the day the process seems to grow and grow. Willing to provide details as requested.

monitoring this with VisualVM, looks like most of the memory (if I'm reading it correctly) is in the "Editor Parsing Loop", it says 64%.

I have the same issue,too.
In parsing period, it showed 'Low memory...'.

Comment 7 Tomas Hurka 2014-05-30 08:19:20 UTC

There is a native memory leak in JDK 8 on Mac OS X. The fact that this is native memory leak explains, why numbers from VisualVM and Activity Monitor are different.

The JDK bug for memory leak is here: <https://bugs.openjdk.java.net/browse/JDK-8041572>

Comment 8 Tomas Hurka 2014-05-30 08:22:05 UTC

Closing as wontfix on NetBeans side.
