Normally this kind of issue comes when paging memory is utilised more.

If yours in linux /unix / AIX ..

issue the command lsps -a this will show how much its being utilised.

if it is more shutdown the instance .. and check for memory agian ..

if its is still there reboot the machine ..

Hi Balaji,

To analyze this kind of issue you should follow note 742395.

It is quite simple to detect what is causing the high cpu:

1. Find the thread that is consuming the CPU (in the note you can see how to do it for all the OS)

2. Take a thread dump in the JVM.

Now you just need to find in the thread dump you took from the JVM the thread and see what he was doing in the thread dump.

In this way you can search this thread for notes to see if it is a bug or something like that and fix it.

I hope it helps.
