zhouxu commented on OAK-8602:
-----------------------------
After this problem occured I try to use plumbr to collection the jvm dump
imformation.For get the imformation quickly that I set the jvm parameters like
this(JAVA_OPTS=-Xms128m -Xmx512m).The same problem comes again.
I also found some answers on Internet and then not good for me.
Actually,the way of we use oak is doubtful.
In this case,I request the backend API to save node.When the web application
startup the oak repository is created.The repository will shutdown at the web
application context was destoryed.
Each request can create a node and need get session in the start of the request
then release session in the end of the request.I create 10000 nodes that means
to get session and release 10000 times.Maybe that's incorrect.
When run junit test in local I open the repository in the setUp() invoked and
close it in the tearDown() method.I create hundreds of thousands node in one
session and it's works well. [~reschke]
