ICMP Type:8 Code:137

We have been seeing a good number of ICMP - echo requests coming in bursts having a code of 137 in the last couple of 
days.  The burst do not last long but are sometimes preceeded by a traceroute.  No other traffice follows from the 
source hosts.  There is no payload in the packets.  My research into what or why this is happening has turned up 
nothing. 

Has any one heard of any attacks or recon using this code?
