In 32bit linux, the userland memory space is probably limited to 3GiB. But 3GiB is not so small. I doubt if there are some memory leaks. Maybe you can use the gc module to diagnose what python objects are in the memory. https://docs.python.org/2.7/library/gc.html > Best Regards, > Soe Ye Htet > > On Sat, Sep 8, 2018 at 7:50 PM Soe Ye Htet <soeyehtet1...@gmail.com> wrote: > > > Dear RYU Team, > > > > I think the the out of memory message is occured due to a lot of packet-in > > message is generated from Switch to Controller.
