running newton with networkin-odl boron, configured to V2 and learn mode ona devstack machine.

I run scripts that create a topology and remove it several times.

#for i in `seq 1 100`; do ./run_tempest.sh test_show_subnet; done

after lots of loops, the JAVA crash and as a result there is no KARAF running.
I could see that the free memory almost drops to 100KB and the system use also the swap memory.

in the attached log files,
the Java process was kill on date 5-Dec-2016, at time 18:22
