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).
