How to find out the root cause of the problem? I see the file "core-java-2951-1384969911" created with a 2MB core dump. Do I need to debug the main dump? if so, how do I do this?

Since a core dump is just an initial dump of the current process data, one thing I do is convert it to a bunch of heaps. You can use jmap for this:

jmap -heap:format=b <java-executable> <core-file>

, , , , . ( 20 .) , java, . , , jmap java. (jmap jdk java 1.4.2.)

, heap.bin, jhat. ( JVisualVM, - , , .) , jmap (jhat JDK 1.6), , , jhat, JDK. Java 6, :

jhat -J-Xmx1024M heap.bin

, , . , "1024". , ( ), 2 , Java Windows. , , jhat, , . , jhat 7000. - jhat, ( ": 7000" ) , JVM.

UPDATE: , , JMap. , , :

jmap -dump:live,format=b,file=heap.bin <java-executable> <core-file>
