Which process is using the CPU, ssh or sshd?  If it's sshd, does setting 
ListenAddress in sshd_config to listen only on the address that's live 
and restarting sshd make any difference?

gdb is probably not going to help much here, instead trace attaching 
strace to the process: run "ps -eaf" and pick out the pid of the 
process, then run "strace -p [pid]" on that particular process (be aware 
that it will probably generate a lot of output).

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
