Smell or Aroma?

Walked into the fermenting chamber, (spare bedroom), looking for something unrelated to beer, (yes that happens sometimes), and there was a very strong sickly/sweet odor. Upon further investigation I found it was coming out of my airlock! This can't be good! Posted to the club message board and response I got was "All is well. Let it finish and drink it." OK, I'll wait. Could be the yeast I used, it was Safale 05, never used that before, also this was my first partial mash. Keeping my fingers crossed......
