High CPU load

[ghost]

When deploying the snoopee-service on a payara-full along with the other services the cpu load of the jvm rises to 80%. This happens on a windows 10 and a debian 8 machine, both running Java 8.

To precise the error:

The high cpu load occurs after invoking a method of SnoopEEServiceClient after a long idle time (1 hour). This happens on Arch Linux 64Bit. Is there something I should consider when injecting the SnoopEEServiceClient?

Ok, after a long freeze time a NoClassDefFoundError was shown, which is crazy, because the class is included in the war file. The log of the payara server is also full of

To many open files

warnigs. Have you encountered this problem also? Is the solution to raise the open file limit (with ulimit -n)?

If you are interested in the log I can send it to you by email.

The problem was that the open socket connections, especially from the heart beat, were never closed.

Here is the exception.

[2017-03-14T04:25:35.479+0000] [Payara 4.1] [WARNING] [] [sun.rmi.transport.tcp] [tid: _ThreadID=108 _ThreadName=RMI TCP Accept-8686] [timeMillis: 1489465535479] [levelValue: 900] [[ RMI TCP Accept-8686: accept loop for [SSL: ServerSocket[addr=/0.0.0.0,localport=8686]] throws java.net.SocketException: Too many open files (Accept failed) at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.AbstractPlainSocketImpl.accept(AbstractPlainSocketImpl.java:409) at java.net.ServerSocket.implAccept(ServerSocket.java:545) at sun.security.ssl.SSLServerSocketImpl.accept(SSLServerSocketImpl.java:348) at sun.rmi.transport.tcp.TCPTransport$AcceptLoop.executeAcceptLoop(TCPTransport.java:400) at sun.rmi.transport.tcp.TCPTransport$AcceptLoop.run(TCPTransport.java:372) at java.lang.Thread.run(Thread.java:745) ]]

So, I'll fork the project, commit my changes an do a merge request.
