Pinned topic rmscok can not work for udp4 PCB

‏2013-05-06T07:01:46Z |

I want to  identify the process which connect to 203.143.136.196  udp/53(DNS) port.

But failed.  Anybody know how to identify the process, thanks!

When I run "rmsock" it report error and generate one core file in current path directory.

149.131.188.25 is  host  "AAA". AAA use different local different udp port tries to connect 203.143.136.196 53/udp port each time. The interval estimate time should be 0.1 second.

AAA:/etc/perf/daily # netstat -Aan |grep 196
70ee7300 udp4     206      0  149.131.188.25.65369  203.143.136.196.53    
AAA:/etc/perf/daily # netstat -Aan |grep 196
71497300 udp4     206      0  149.131.188.25.33611  203.143.136.196.53    
AAA:/etc/perf/daily # rmsock 71497300 inpcb
Segmentation fault(coredump)
