[Bug 601307] [NEW] CPU usage jumps to 100% upon launching eclipse

[Nazish Hussain]

Public bug reported:

Today Ubuntu 10.04 64 bit, gave me an option to upgrade my packages and
it included an update to the kernel too. I upgraded from kernel
2.6.32-22-generic to 2.6.32-23-generic. I installed all the other
updates too.

After the upgrade my system became terribly slow each time I started
Eclispe 3.5 Galelio. The previous version of the kernel never displayed
this behavior. Surprisingly, the CPU usage remained at 100% even after
killing the "java" process using system monitor.

I have attached the CPU usage screen shots when using kernel
2.6.32-22-generic and 2.6.32-23-generic, when running eclipse.

I downloaded java from the SUN website, the following is the Java information:
java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode)

This bug never occurred when using the previous version of the kernel,
and happed only after I upgraded to the newer Kernel.

Let me know if you need any other information from me.
