thousands bandwidth_in messages in syslog

[Andrea Ganduglia <nonews.org@gmail.com>]

On my new server, I see thousands bandwidth_in messages in syslog like:

May 18 14:05:39 hostname kernel: [1649426.288863] BANDWIDTH_IN:IN=eth0
OUT= MAC=00:21:5e:xx:xx:xx:xx:xx:xx:xx:db:e1:08:00 SRC=95.**.**.**
DST=62.***.**.*** LEN=84 TOS=0x08 PREC=0x40 TTL=52 ID=3172 DF
PROTO=TCP SPT=51390 DPT=22 WINDOW=2506 RES=0x00 ACK PSH URGP=0

how can I disable this?

Thanks
