So finally, with Thomas hints I get jstack information and some dump :
* jstack result when server gone up to 3.6 of load (and JVM freezed) : 
http://pastebin.com/m53d654f8
* hprof dump after having killed -QUIT java main process : 
http://pastebin.com/m8631370

Lucene/Jackrabbit search stuff seem to be involved in TIME_WAITED thread 
and exceptions.

Thanks for any help.
