VSM error messages regarding mts?

[PeterLB01]

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?

Hi Peter,

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

(): NO SPACE sap=306, sap_opt = 0x1, hdr_opt = 0x4, rq=27262(37273187), lq=0(0),

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.
