By high traffic do you mean amount of messages or actual volume?
AFAIK, +zdbbl is more of a possible cure for volume and battling things
like TCP incast. However, in our case the network utilization does not
go over ~20%, so I don't think TCP incast is playing role here. The
number of messages is quite large, though.
I bumped it to 32MB in any case, can't hurt.
