Hi, Furthermore I also tried analyzing the JVM using Java Mission Control, but it also get stuck when the OOM occurs. The CPU usage is very high.
I took a brief look at the heap dump using jvisualvm. And as far as I understand, the following thread is the one producing the OOM error, when iterating a linked list. "NioBlockingSelector.BlockPoller-1" daemon prio=5 tid=62 RUNNABLE at java.lang.OutOfMemoryError.<init>(OutOfMemoryError.java:25) at java.util.HashMap.newKeyIterator(HashMap.java:840) Local Variable: java.util.HashMap#416322 at java.util.HashMap$KeySet.iterator(HashMap.java:874) Local Variable: java.util.HashMap$KeySet#291 at java.util.HashSet.iterator(HashSet.java:153) at sun.nio.ch.SelectorImpl.processDeregisterQueue(SelectorImpl.java:127) Local Variable: java.util.HashSet#745 at sun.nio.ch.EPollSelectorImpl.doSelect(EPollSelectorImpl.java:69) at sun.nio.ch.SelectorImpl.lockAndDoSelect(SelectorImpl.java:69) Local Variable: java.util.Collections$UnmodifiableSet#9 Local Variable: sun.nio.ch.Util$2#6 at sun.nio.ch.SelectorImpl.select(SelectorImpl.java:80) Local Variable: sun.nio.ch.EPollSelectorImpl#6 at org.apache.tomcat.util.net.NioBlockingSelector$BlockPoller.run(NioBlockingSelector.java:327) Regards, Chamila de Alwis Software Engineer | WSO2 | +94772207163 Blog: code.chamiladealwis.com On Tue, Dec 16, 2014 at 1:29 PM, Chamila De Alwis <[email protected]> wrote: > > Hi Shashika, > > I am also coming across this issue.
