Someone is sending too many icmp requests to your machine and the kernel
isn't answering that cause you've ICMP_BANDLIM enabled in your
kernel. This option tells the system not to reply to such requests when it
reaches the limit (which is, by default, 200 packets per second).
To change it just set the proper variable with sysctl(8), like this:
[root@ttyp2:~]# sysctl net.inet.icmp.icmplim
net.inet.icmp.icmplim: 200
[root@ttyp2:~]# sysctl -w net.inet.icmp.icmplim=300
net.inet.icmp.icmplim: 200 -> 300
or disable that option in the kernel (which isn't good, BTW).
Hope it helps,
