    Dead locked threads encountered when upgrading from 3.2.3 to

    atait Newbie

      We have upgraded our Jboss instance and the JDK to 4.0.3 and 1.5.0_06 from 3.2.3 and 1.4.2_03 respectively. Our OS platform is Linux Enterprise 2.6. On the upgraded platform our web application runs for about 12 hours before becoming unresponsive. I'm attaching the JVM stack dump as it indicates many locked threads. I have been looking at this for a while and could use some assistance from others with more experience.

      Notice that TP-Processor137 has locked the java object that most other threads are waiting for. This thread is waiting on a condition but it's not clear on what condition and why it is not completing. It appears that this is the root cause. Other thread dumps indicate the same scenario.

      Any light that can be shed is appreciated.

          After looking at the javax.management code, it appears that the thread TP-Processor137 is constructing an Mbean. Is there any other reason these methods would be called? Trying to get some traction on this ....

            By moving to jdk5 you are using the jdk implementation of the jmx components and it appears that the jdk ObjectName is causing contention.

            You can disable this registration by setting registerRequests="false" on the connector.

              I can see this property in JMX, although when I submit the change I get the following error:

              Cannot find setter method setModelerType

              I see a JIRA entry for this issue with no resolution at this point. It appears this will be corrected in 4.0.4.

              I grepped through config for this property with no success. Is there some place I can set this manually?

              Thanks

                Here's the link to Jira issue:

                http://jira.jboss.com/jira/browse/JBAS-1169

                Is there a jk.properties file deployed with jboss4.0.3? I believe this is the right place to make the suggested configuration. I'm not finding this file in our deployment.

                  Does Jboss provide a way to set this attribute <registerRequests=false> in 4.0.3?

                  JMX throws the error described above when attempting to apply changes to this Mbean. This boolean value does not appear to be managed in a config file. The java class "HandlerRequest" sets this attribute to true, right in the code.

                    Edit jbossweb-tomcat55.sar/server.xml and add request.registerRequests="false"

                     <!-- A AJP 1.3 Connector on port 8009 -->
                     <Connector port="8009" address="${jboss.bind.address}"

                     request.registerRequests="false"

                      Scott,

                      The config change suggested did not solve this issue. Those waiting threads are likely a side affect and not cause. Note that this issue (accumulation of waiting threads, leading to full degradation of performance) can be duplicated by running our link checker against all 12 web sites. This activity, it seems, would be similar to a crawler indexing our sites. The assumption is that this activity is responsible for initiating the downward spiral in performance ending in no response from the server. From testing it seems this is not necessarily related to the level of concurrent activity. If we link check one site at a time, after a number of sites, we end up in this state. Interesting to note that if we link check the same site repeatedly, the server does not progress to this bad state. Instead some extra threads are created on the first test, subsequent tests do not increase the thread count. Of course when we link check all at once, threads pile up, performance degrades

                      When the server gets in this bad state CPU utilization is tapped. Our environment is running on a 2 CPU box. While in this bad state, one CPU will me maxed (90+ %) the other near (0%). At pretty short intervals (few seconds) the load is swapped from CPU1 to CPU2 and then back again, continuing to swap in this fashion. I assume the JVM is utilizing one CPU at a time.

                      In worst state, thread count (in JVM stack trace) is high, usually over 200. No dead locks are indicated in the JVM stack trace. When the system is healthy, we typically see 80 threads. I took 3 traces a few minutes apart as system performance went from bad to worse. The majority of threads are ?waiting on monitor entry?. The thread traces appear to be all executing, or waiting at a low level in the code (below our application). There are only a few threads in the runnable state. These runnable threads appear to be in normal processing based on thread stack traces, nothing stands out.

                      I?d like to attach the 3 stack traces but these are large. Can I send these via email to get more input?

                      Allen

                        Since JIRA entry has been closed I'm posting back here with update. I have profiled this issue and see the following with respect to garbage collection:

                        As the application is exercised heavily, heap utilization increases and decreases due to GC activity. The heap space used is generally around 100m (according to profiling tool), max heap space is set to 512m. At some point heap utilization drops from a typical peak (result of GC) and flattens out, and GC begins to execute repeatedly (excessively). While this is going on, no additional heap space is recovered (heap utilization appears to be well below the max throughout). It appears that no other processes get a chance to run while the GC continues in this manner for a period of a few minutes. While in this state, CPU is pegged at 100%. After a few minutes GC goes back to one minute intervals and CPU utilization returns to 1% or 2%. Heap usage remains unchanged throughout excessive GC activity and beyond. The application continues to be unresponsive and requires a restart to clean up.

                        I continue to drill in to this. Any additional direction is appreciated.

                        Allen
