Comment 2 Alexander Simon 2016-01-14 08:38:24 UTC 
142,073,264 bytes in 433,656 instances of the class
org.netbeans.modules.remote.impl.fs.RemoteLinkChild

It looks like remote FS does not have protection on "infinite" loop in case
recursive link like to "/usr/bin/X11/X11/X11/X11/X11/...."
Comment 3 Vladimir Kvashin 2016-03-17 13:05:37 UTC 
Yes, the reason is cyclic links. Heap dump shows 4062 remote plain files, 370 remote directories, 243 remote links and and 433656 instances of RemoteLinkChild! You can only achieve this via cyclic links.

So the root cause is quite the same as in issue 258298, which has been already fixed.
