In src/lib/Libifl/pbsD_connect.c, you'll find the following:
/* FIXME: is this necessary?  Contributed by one user that fixes a problem, 
   but doesn't fix the same problem for another user! */
#if 0
#if defined(__hpux)
   /*HP-UX : avoiding socket caching */
   send(connection[out].ch_socket, '?', 1, MSG_OOB);

Can you change that 0 to a 1 and try it?
