Applies to:
Oracle WebCenter Sites - Version 7.6.2 and laterInformation in this document applies to any platform.
Goal
Remote Satellite Server (RSS) or WebCenter Sites is unresponsive, and many threads are observed as blocked, waiting on a lock inside KeyThrottle.execute() method, e,g:
"http-7001-316" daemon prio=10 tid=0x00002aab834c4000 nid=0xd98 waiting for monitor entry [0x0000000059b8e000]
java.lang.Thread.State: BLOCKED (on object monitor)
at com.fatwire.cs.core.util.KeyThrottle.execute(KeyThrottle.java:79)
- waiting to lock (a java.lang.Object)
The full stack trace is:
com.fatwire.cs.core.util.KeyThrottle.execute(KeyThrottle.java:79)
COM.FutureTense.Common.ContentServer.evalPage(ContentServer.java:1222)
COM.FutureTense.Common.ContentServer.execute(ContentServer.java:454)
COM.FutureTense.Servlet.FTServlet.execute(FTServlet.java:129)
COM.FutureTense.Servlet.FTServlet.doGet(FTServlet.java:53)
javax.servlet.http.HttpServlet.service(HttpServlet.java:707)
What is the significance of this?
Would this cause a lock on all managed servers in the cluster and block them all from working?
