RE: Tomcat 3.2.1 JDK1.3.0 on Solaris - processor usage.
Please see my 3rd paragraph. The readme was the first place I looked. I am aware of this bug. It is not what caused our processor usage to spiral. Perhaps I should have said "all our contexts/webapps are configured correctly". -Original Message- From: DONNIE HALE [mailto:[EMAIL PROTECTED]] Sent: 06 April 2001 13:58 To: [EMAIL PROTECTED] Subject: Re: Tomcat 3.2.1 JDK1.3.0 on Solaris - processor usage.
