Nuno, 

I don't have any particular idea what is going wrong.  From the
debug messages it is getting reasonably far.  Under normal conditions
I think that would be the last debug messages though, so it is hard
to judge how much further it got.  In particular, there is no "exiting" 
message despite what might be implied by the word entering message.

I would suggest trying to replicate the request at the command line and
see how that goes. 

ie. 
./mapserv QUERY_STRING='map=wcs.map&SERVICE=WCS&REQUEST=GetCoverage&COVERAGE=landsat_europe&CRS=EPSG:4326&BBOX=-6,40,-5.5,40.5&RESX=0.00027778&RESY=0.00027778&FORMAT=geotiff'


If the problem persists try to boil down the problem and submit a bug
report via bugzilla (or debug it yourself). 

Best regards,
