I should mention that I might have a clue - around the time the crashes
started, I started using HTB with the following configuration:

tc qdisc add dev eth0 root handle 1: htb default 100
tc class  add dev eth0 parent 1: classid  1:1  htb rate 500mbit ceil 1gbit burst 5m
tc class  add dev eth0 parent 1:1 classid 1:2  htb rate 100mbit ceil 1gbit burst 1m prio 0
tc qdisc  add dev eth0 parent 1:2  handle 2:  sfq
tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dport 22 0xffff   flowid 1:2
tc class  add dev eth0 parent 1:1 classid 1:3  htb rate 100mbit ceil 1gbit burst 1m prio 1
tc qdisc  add dev eth0 parent 1:3  handle 3:  sfq
tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dport 873 0xffff   flowid 1:3
tc class  add dev eth0 parent 1:1 classid 1:16 htb rate 50mbit ceil 100mbit burst 512k prio 3
tc qdisc  add dev eth0 parent 1:16 handle 16: sfq
tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dst 161.53.160.16 flowid 1:16
tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip src 161.53.160.16 flowid 1:16
tc class  add dev eth0 parent 1:1 classid 1:100 htb rate 100mbit ceil 300mbit burst 1m prio 2
tc qdisc  add dev eth0 parent 1:100 handle 100: sfq

HTB actually complains a little bit about r2q/quantum (too big), but that's
not supposed to be so harmful.
