is it possible that you use the unified output plugin?
In this case all rebuild packets from stream4 which raise an alert
are stored as the original individual packets. The first is associated
with the alert message and all further parts are labeled as "Tagged
So in this case it will not help to suppress it this way. I fear
you have to tune your rules to reduce the number of alerts. (Or
you can use another output method, AFAIK only the unified output
plugin decomposes the rebuild packet with "Tagged Packets".)
