  OK.

  No, it should work...

  My guess is that the home server is being inserted into the tree, but for some reason it's unable to find it.  i.e. the data being used for add / find are different.

  Maybe you have src_ipaddr set in the home server configuration?  The stats lookup assumes the the source IP is INADDR_ANY.
