coupled blow up

[redhat007]

Dear
for coupling roms and swan in my application, at first i have run roms and swan separately with out problem. then coupled them with following flags:
#define WEC_VF
#define WDISS_WAVEMOD
#define ROLLER_RENIERS
#define UV_KIRBY
#define SURFACE_STREAMING
#define BOTTOM_STREAMING
#undef AVERAGES_WEC
but it blows up very soon (after 18 min)
would you please tell me what is problem and how i can fix it?
Cheers

suggest that you take it one step at a time.
undef bottom streaming
undef surface streaming
unef roller reneirs

and see if that works. then slowly add these back in.
