[ovs-dev] Error in floodlight console

[Hossein Mousavi Nejad]

Hi
In my scenario, I defined a network consist of a floodlight controller, 5
ovs switches and 5 hosts using this VM:
http://csie.nqu.edu.tw/smallko/sdn/stoachastic_switching.htm

I develop my application using python and use REST API to add flow entries
and select group table in OVSs.
when I add several flow entries using a loop in all my 5 switches by API,
some flows in some switches does not add and I receive this error in
floodlight console:

I want to know how can I solve this error.
