Development enviroment help (Idea freeze problem)

[erolozcan]

My problem is most probably not directly related with OpenBaton, but it could possible that someone, who is contributing this project, experienced the same problem.

I am changing codes of some OpenBaton projects (NFVO, generic-vnfm, openstack4j-plugin..).
IntelliJ is freezing when i tried to run (NFVO - Application.java) my changes directly from Intell Idea. The Idea UI stop responding to any action. No thread dump is generated from Idea. I also cannot generated thread dump with kill -3 . There is no clue in the log files (idea logs, syslog, dmesg, kern, Xorg, openbaton etc.).

I can run some non OpenBaton projects without freeze. But those projects are not big as OpenBaton. I increased Xmax size of Idea, but nothing changed.

Do you have any suggestion to solve this problem?

How much memory has your Ubuntu virtual machine? Try to monitor the available memory when you launch the NFVO from Intellij IDEA. FYI I use a develop environment with 16 GB of RAM and I've never had such problem so far.
