  Please upgrade.  2.2.6 is 3 years old, and there have been fixes to the v2 branch.

  Maybe there's a fix in v2.2.9, in which case you can upgrade to that without changing anything.

  Otherwise, upgrade to v3.  It's the currently supported version.

  If the home servers are unresponsive, there isn't much you can do.  Tho v2.2.9 has fixes to proxying which may help.

  Why?  FreeRADIUS should Do The Right Thing.  i.e.

  That's a bad work-around to a potential bug in the server.  Why not fix the underlying problem?
