Comment 2 Ondrej Vrabec 2014-04-22 06:34:34 UTC 
i can see this in the log:
WARNING [org.netbeans.modules.subversion.DiskMapTurboProvider]: Subversion cache contains 1,686 locally new (uncommitted) files. That many uncommitted files may cause performance problems when accessing the working copy. You should consider committing or permanently ignoring these files. Candidates for ignoring are: [/UCConnect/NetBeansProjects/UC_Softphone_JPhoneLite/src/resources: 1,686 new files]

i strongly suggest you svn ignore this folder: /UCConnect/NetBeansProjects/UC_Softphone_JPhoneLite/src/resources

All of memory is more or less consumed by FileUtil-Refresh-All task. It collects hundreds of thousands of files in rg.netbeans.modules.masterfs.filebasedfs.fileobjects.BaseFileObj.refresh
 and more interestingly in a single call to org.netbeans.modules.masterfs.filebasedfs.children.ChildrenSupport.
Looking at the heap dump folder /UCConnect/NetBeansProjects/UC_Softphone_JPhoneLite/src/resources contains around 300 000 files !!!!

chakrit_w: why do you keep 300 000 files in /UCConnect/NetBeansProjects/UC_Softphone_JPhoneLite/src/resources??? Lot of them in the format IMG.png.HASH. Remove them.

> Looking at the heap dump folder [...] contains around 300 000 files !!!!
Working with such a huge project has quite high memory requirements.
Please consider removing/hiding/ignoring the folder. Or increase the Xmx parameter if you really need to keep the files in your project.
