Comment 2 Vladimir Kvashin 2016-05-13 19:18:42 UTC

0.5G (retained) in 188K instances of FolderConfiguration

The project seems to be under SVN.
It's probably mixed or simple remote, at least remote is present, but source files are local.

Comment 3 Alexander Simon 2016-05-16 07:28:07 UTC

About 180 Mb in 6 cloned MakeConfiguration in class:
org.netbeans.modules.cnd.debugger.common2.debugger.debugtarget.DebugTarget

Comment 4 Alexander Simon 2016-08-31 22:04:41 UTC

Debugger holds 6 cloned configurations.
Problem is in debugger.

Comment 5 Alexander Simon 2016-09-01 08:31:47 UTC

I looked on the same problem and reduced size of MakeConfiguration in about 2 times (see bug #257744).

But problem in memory leak in debugger. Debugger do not release a cloned MakeConfiguration (or keep extra configurations).

Comment 6 Alexander Simon 2016-09-01 13:08:07 UTC

The change set
Changeset: http://hg.netbeans.org/main-silver/rev/72dc88d19f7f
should fix the issue.
