CPU Utilization

mail2mphani · 09-13-2010, 07:31 AM

Dear All

I am facing a problem in rhel4(2.6.9-34.ELsmp). My application is java(java version "1.6.0_16") based Enterprise application. At present our application running on sun vfire 440. It has 8 processors with2.4GHz and 8GB Ram. When my application starts some times the cpu utilization goes up to 99%. Give the solution for this.
