Hi,
I seem the number of "file descriptors" hits the limit of its max.
In most case, 1024 is the max per process and "/proc/sys/fs/file-max" contains
the max of whole of OS.
e.g.)
$ ulimit -n
1024
$ cat /proc/sys/fs/file-max
800471
Thanks,
Iwase

Hi everyone,
I have written a ryu application, it works well with small topology, but
when I create a topology which has 80 switches, I obtain the following error:
hub: uncaught exception: Traceback (most recent call last):

I want to know how I can fix the error?
Thanks,
