updated MYFACES-1162: ---------------------- > _ComponentAttributesMap.getPropertyDescriptor appears to get hung in a > HashMap under peak load. > ----------------------------------------------------------------------------------------------- > > Key: MYFACES-1162 > URL: http://issues.apache.org/jira/browse/MYFACES-1162 > Project: MyFaces Core > Type: Bug > Versions: 1.1.1 > Environment: Solaris: SunOS mkeux507 5.9 Generic_117171-11 sun4u sparc > SUNW,Sun-Fire-V440, Java: 1.4.2_08, WAS: V5.1.1.6 > Reporter: Larry Evers > Priority: Critical > Attachments: native_stdout.log > > Our production ECS application (built with WSAD V5.1.2) is running on WAS > 5.1.1.6 on 6 (4 processor) Solaris boxes each running 4 VM's for a total of > 24 app server instances. Each App server is tied directly to a web server > (IBMHTTPD). A load balancer at the front selects the web server to use based > on equal weighting. We are not using session clustering so if an app server > fails the transaction is lost. > Our application is a JSF application running Apache myfaces V1.1.1. > Under peak load we appear to get threads hung. As more threads get hung the > cpu usage goes up on the box, eventually reaching 100%. > We stopped the web server for this app server so no new activity would hit > the app server. > We then did a series of kill -3 to see what the threads were doing. CPU > stayed high. > 8 transport threads (341, 339, 8, 7, 6, 5, 3, 2) appear to be hung in a > HashMap for each kill -3. > Sample output of native_stdout.log (attached) > "Servlet.Engine.Transports : 339" daemon prio=5 tid=0x0049ba38 nid=0x74c0 > runnable [cdcfb000..cdcffc28] > at java.util.HashMap.put(HashMap.java:382) > at > javax.faces.component._ComponentAttributesMap.getPropertyDescriptor(_ComponentAttributesMap.java:203) > at > javax.faces.component._ComponentAttributesMap.get(_ComponentAttributesMap.java:124) > at > javax.faces.webapp.UIComponentTag.removeFormerChildren(UIComponentTag.java:268) > at javax.faces.webapp.UIComponentTag.doEndTag(UIComponentTag.java:241) > at org.apache.jsp._cardStatus._jspService(_cardStatus.java:4020) > at > com.ibm.ws.webcontainer.jsp.runtime.HttpJspBase.service(HttpJspBase.java:89) > ....truncated -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
