Hi, I tested tomcat 6.0.10 using jmeter. I found the following problem. I defined three thread groups: ============================First thread-group============================ thread Properties: Number of Threads(users): 50 Ramp-Up Period(in seconds): 10 Loop Count: 1000
HTTP Request path: /examples/servlets/servlet/HelloWorldExample Constant Timer Thread Delay (in milliseconds): 10 ============================Second thread-group============================ thread Properties: Number of Threads(users): 50 Ramp-Up Period(in seconds): 10 Loop Count: 1000 HTTP Request path: /examples/jsp/tagplugin/foreach.jsp Constant Timer Thread Delay (in milliseconds): 10 ============================Third thread-group============================ thread Properties: Number of Threads(users): 1 Ramp-Up Period(in seconds): 1 Loop Count: 1000 HTTP Request path: /manager/status Send parameter with request: XML(Name) true(Value) Constant Timer Thread Delay (in milliseconds): 1000 =========================================================================== I found tomcat 6.0.10 will use 100% CPU in a few minutes, then I stop sending http request in jmeter. After that, I accessed another jsp page: /examples/jsp/jsp2/el/basic-arithmetic.jsp in web browser , but tomcat gave me the following response: HTTP Status 500 - type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: java.lang.OutOfMemoryError: Java heap space org.apache.jasper.servlet.JspServlet.service(JspServlet.java:274) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) root cause java.lang.OutOfMemoryError: Java heap space note The full stack trace of the root cause is available in the Apache Tomcat/6.0.10 logs. I installed Tomcat 5.5.20 and did the same testing, I could not produce this problem on tomcat 5.5.20. Thanks. Arden __________________________________________________ Do You Yahoo!? Tired of spam?
