Valeri - just be aware that that post is from 2004. &nbsp;So it's for ... Tomcat 4? &nbsp;In any case, Tomcat doesn't ship with the server.xml spec &nbsp;shown in that question. &nbsp;And there are not known problems with connectors going to 100% in Tomcat. &nbsp;<br />
<br />
As I said, the likelihood is high that this is a database problem. &nbsp;Since the asker believes that the problem is in JasperReports, it could also be a problem with a bad report specification, but the db queries and handling is the place to start. &nbsp;Naive users of databases and Jasper also have a tendency to never close db connections, which will also take the system to 100% after a while.

I am running Tomcat 7 to use Jasper Reports on CentOS release 5.6 64 bit. Many times the CPU load avg on machine goes very high (above 4) and remains there unless I don't restart tomcat. Top shows java taking over 99% CPU. <br />
<br />
This is only running Jasper Reports and no other Java apps are there. Is there a way to find out which report has made this running for that long?

Tomcat High CPU Load

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java

Java application servers that support the Java EE platform and features include JOnAS from Object Web, WildFly (formerly JBoss AS) from JBoss, Geronimo from Apache, TomEE from Apache, Resin Java Application Server from Caucho Technology, Blazix from Desiderata Software, Enhydra Server from Enhydra.org, and GlassFish from Oracle. Commercial Java app servers include WebLogic by Oracle, WebSphere from IBM and the open source JBoss Enterprise Application Platform (JBoss EAP) by Red Hat.

Java App Servers

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.
