Hi,
Well, which version of Ryu (also OVS on Mininet?) are you using?
And please check whether re-connections between Ryu and your switches occur or
not. If re-connections occurs too frequently, your switches might try to
establish new connections regardless of Ryu could close socket successfully,
then Ryu unexpectedly eats up file descriptors and reaches its limit.
Thanks,
Iwase

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
