Hi, Since I have just refactored the eviction policy last week, I have tried your test case on the latest code on jboss-head. I don't see any error right now. So can you try it yourself to make sure the problem is resolved? I will incorporate your test case.

Ben, Now it's working much better, it takes some time to get this error. But unfortunately, it's still there. Seems it heavily depends on system load.

I've just put latest jboss-cache.jar into jboss and run my application testunit. It's about the same I used above. It puts as much as possible my cached objects to cache. Shortly after start I noticed that number of cached object keep rising far above limit (1). I stopped my testcase. Then, while there's no any activity with cache, it jboss stdout I see that on each eviction step the same exception it thrown.

I encounter the same problem, the exception for the no-existing node is raised again and again. Maybe the problem is again related to the Bug: [ 1013153 ] infinite loop in LRUAlgorithm.prune There has been a discussion about this, the related bug has been closed, but I see the problematic code again in LRUAlgorithm.removeFromQueue: ne.getPrevious().setNext(ne.getPrevious()); ne.getNext().setPrevious(ne.getNext()); This infinitely blocks the EvictionTimerTask, but maybe I am wrong? -uwe View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3846024#3846024 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3846024 --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 ___ JBoss-Development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

Can you guys try it one more time by getting the latest jboss-head? It is actually not a serious error, per se. Here is why. What happened was in TreeCache, it will do another nodeModified event notification after the parent (leaf node has no problem) node is evicted. So you see, it will loop back to eviction policy again. And therefore could not found the evicted node. Bela and I have found a solution to stop the notification in this case. So the problem should be solved. If not, it is something else I need to look at.

Hi, I can easily reproduce the java.lang.OutOfMemoryError with the testcase, but I am not sure - if this is really a bug. Could it be possible, that simply the parameters in local-eviction-service.xml are not optimal for the use case and the environment? -uwe View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3846199#3846199 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3846199 --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 ___ JBoss-Development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

Guys, I don't think it is a bug. I can also re-produce the OOM error myself here as well. The key is the load is simply not realistic if we have multiple threads that are generating put and get all the time and thus exhibiting 100% CPU. A more realistic use case will requires a random sleep in between put/get so the eviction timer has time to pocess those. In another persective, to tune it up, you can decrease the parameter "wakeUpIntervaleSeconds" so the timer wakes up more often. But again there is a limit that it can do that, especially, when it is *local* mode of which put/get is really quick. If it is replicated mode, then the bottle neck will probably not be CPU bound anymore. Thanks a lot for all your help. -Ben View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3846239#3846239 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3846239 --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 ___ JBoss-Development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

Uwen, Ben, Of course I do not consider this particular out of memory exception as a bug. The thing is OutOfMem CAUSED by exception which is this thread's topic. In my last post - take a look - first this exception appeared, it repeated with each eviction cycle effectively stopping eviction. This caused rising number of nodes far behind maxNodes limit, and, AS A RESULT, OutOfMem. Again, as you see in my last post's log extracts, cache keeps trying to remove the same node, _which is not exitst in cache at the moment_, causing exception. THIS is a bug, imho.

Ben,
Here's a test unit which reproduces this bug in 100% run. default
local-eviction-service.xml is taken with no changes. _defatlt_ region is used with
maxModes=5000. Here it is:
| public void test2() throws Exception {
| cache = new TreeCache();
| PropertyConfigurator config = new PropertyConfigurator();
| config.configure(cache, "META-INF/local-eviction-service.xml");
|
cache.setTransactionManagerLookupClass("org.jboss.cache.DummyTransactionManagerLookup");
| cache.start();
|
| for (int i = 0; i < 50; i++) {
| new Thread() {
| public void run() {
| while (true) {
| int i = (int) (Math.random() * 1);
| try {
| cache.put("/test/node"+i, "value", new Integer(i));
| Thread.sleep(10);
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
| }
| }.start();
| }
|
| while (true) {
| Node node = cache.get("/test");
| int count = node == null || node.getChildren() == null ? 0 :
node.getChildren().size();
| log.info(new Date() + " Nodes: " + count);
| Thread.sleep(1000);
| }
|
| }
|
Here is the output a get:

Ben, just to assure it's not an artificial case: the bug appears in my real application where cache is to cache stock charts which are produced in relatively long time but frequently requested from web (8-digit requests daily). I reproduce this bug just running some 10 threads in JMeter making web requests, which is far less then it's going to be in production.

Uwe, That is good news, isn't it? Octopus, can you download the latest jboss-head and test it again? I have minor changes checked in yesterday. Make sure Region.java now has a warning message for reaching over the threshold value. If there is still an issue, I'd like to track it down. I ran your test case yesterday for one hour but couldn't reproduce it with the new code. Make sure you have the region setup correctly in the xml file. And also reduce the wakeUpIntervalSeconds to 1 (second).
