idrac discards

hi

we have many dell servers across the network. with IDRACs of 6/7/8/9

all the idracs are vlan tagged. 

for some reason, all idrac 6 and 7 (maybe 8, not sure), suddenly every 1 or 2 days blast the switches with discards.

any idea why that is?

when it happens, it happens at once, all of the together. as if a scheduled "something" is trying to do it's job.
