Haven't seen this before, but I'll try to help you out. Sounds like
something IPv6 related... I would need to know more details though.

o Which version of ssmping?
  And from source or RPM or...

o Description of the problem
  Is this only at startup or when you receive a query? Does it exit or
  is the process still running?

o Output
  It would be good to see exactly what the output is

I guess it could also be useful to know kernel version and whether you
have IPv6 configured (output of ifconfig -a might be of help).
