Servers can die. - doxhdr: same problem. - do_group: should return long.  variable newserver should be signed   long, else it cannot detect error condition of getgroup(). - do_group: splint annotation typo. - processupstream: variable newserver should be signed long (same error   condition problem).  Unchecked though. - processupstream: fix 2 memleaks.
