I do: the default setting leaves packets beyond the depth of the queue 
dropped, which, in the case of SIP requests and some responses, causes 
them to be retransmitted, which creates a positive feedback loop. 
Letting them stack up allows more of them to be attended to eventually, 
reducing that dynamic.

But telling the OS network stack to hold more packets because you can't 
process them fast enough isn't a solution to the problem of not 
processing them fast enough. You're infinitely better off just 
processing them faster.
