Bug Description
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.
