netbeans is so slow

[mesocool]

I am using netbeans 6.0 and it becomes so slow after a few compiles with tomcat. My whole ubuntu is frozen and nothing can be clicked on. I am using sun's jdk. Is there anybody having the same problem or do I need some special configurations to solve this problem?

Thanks..

Sounds like Java is hogging all your RAM or CPU.

Does "top -i" or "free -mol" give you any clues?

I found a similar problem with an Eclipse plugin when parsing XML files, but for me NB has been fine with Tomcat

The problem is with the permissions set on the JDK folder and contained files, I guess. You can look at the following link for help

thanks everybody.

I just found that even I load a large pdf file with evince. My system froze until the current page was loaded. Ubuntu works fine on my desktop. But it becomes slow sometimes (not all the time) after I use it for a while.

Strange.
