Strange traffic on NetVanta 4430

Hello,  I have an old Adtran NetVanta 4430 running some pretty old code.  I did a 'debug ip icmp' and noticed a lot of outbound traffic with a source IP of 127.0.0.2 and destination IPs of various kinds. 

Examples:

ICMP SEND: From 127.0.0.2 to 183.134.7.66 Type=3 Code=13 Length=20 Details:communication administratively prohibited

ICMP SEND: From 127.0.0.2 to 92.63.194.18 Type=3 Code=13 Length=20 Details:communication administratively prohibited

ICMP SEND: From 127.0.0.2 to 92.53.90.182 Type=3 Code=13 Length=20 Details:communication administratively prohibited

ICMP SEND: From 127.0.0.2 to 210.123.149.84 Type=3 Code=13 Length=20 Details:communication administratively prohibited

ICMP SEND: From 127.0.0.2 to 111.171.214.37 Type=3 Code=13 Length=20 Details:communication administratively prohibited

ICMP SEND: From 127.0.0.2 to 178.19.108.74 Type=3 Code=13 Length=20 Details:communication administratively prohibited

Any idea what might be generating this traffic, and why? There are no corresponding receive entries. Thanks.
