Hi people, i'm getting spammed with the following error messages on my Nexus 1000v VSM (It's running as a HA pair):

Haven't been able to find anything related to it on google. Can anyone help me out?
Always provide the software version. Then we will definitely help you.
Sounds good. :-)

Do you have netflow on your running configuration? Seems to me that you are exporting a lot of flows from the line card on to the supervisor. Decoding this message:
Nexus-vsm %KERN-2-SYSTEM_MSG: mts_is_q_space_available
306 corresponds to the netflow's Service Access Point ( SAP).
rq = receive queue of netflow is saturated.
Try one of the following:
a) Increase the inactive timeout
b) Increaste the active timeout.
c) check the number of interfaces you have netflow on .( limit is 256 switch-wide)
Even with a, b and c, if you have traffic that is shortlived or voluminuous you might see this error.
