This is lasts for long period..
Usually happened when hosts in that class perform download or online 
streaming.

I tried to set to zero:
class htb 1:3003 parent 1:4 leaf 3003: prio 0 rate 4Kbit ceil 24Kbit burst 0b 
cburst 0b
class htb 1:1000 parent 1:2 leaf 1000: prio 0 rate 32Kbit ceil 48Kbit burst 0b 
cburst 0b
 rate 4332bps 5pps backlog 52p

results: still exceed around 50 - 80 bps
