When the editor is doing nothing (of course i'm not even move with my mouse), memory is increasing about 100 kb every 2-3 seconds. Product Version: NetBeans IDE Early Access for PHP (Build 200804221056) Java: 1.6.0_06; Java HotSpot(TM) Client VM 10.0-b22 System: Linux version 2.6.24-1-686 running on i386; UTF-8; pl_PL (php) Userdir: /home/shadzik/.netbeans/6.1ea-php
How long did it last? Can you reproduce it? Please attach several thread dumbs taken during the time when it happens and attach them to the issue description (see http://wiki.netbeans.org/GenerateThreadDump). Even when the user is not typing there are many background processes running and the described behavior doesn't have to mean there is something wrong unless the memory consumption goes beyond some reasonable levels.
I think it was my mistake. After several minutes memory goes down. I didn't know that there is some process going in background, so I'm sorry for that bug report.
