Cannot setup >1 cipe interfaces

hi,

i try to setup cipe for more than one roadwarrior.
i tested with one cipe tunnel and it worked,
now i try to setup a second cipe interface on redhat server,
so i copied the options.cipcb0 file to options.cipcb1 and altered the
settings in the new options.cipcb1 file.
when i start the ciped service it tries to start the cipcb1 and the the 
cipcb0,
but cipcb0 fails with error in log:

ciped-cb[xxxxx]: opendev: bind: Address already in use


can someone tell me what i am doing wrong?

regards, wolf
