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. This is because my current
focusing is about the dynamic routing which need to be changed by the RYU
controller. Currently, my setting is generating the packet-in message from
OF Switch without buffer ID. I think that is main cause of memory problem
in RYU controller. Is my guess wrong? When I see the main root cause, i
will share in this group so that next person can avoid the similar problem.
Best Regards,
Soe Ye Htet
