Maybe, maybe not. Some pipes tend to gurgle, even if you are an experienced pipe smoker and do everything right.
What are you smoking and is it too moist? Some over the counter tobaccos are notorious for being too moist, and that can lead to gurgling. Even "higher quality" tobaccos are sometimes shipped a bit on the moist side. Seems that the optimum moisture for processing tobacco is somewhat higher than what most people find to be the optimum for smoking.
So, you could try drying your tobacco a bit before you smoke. Spread out some tobacco on a paper plate or coffee filter or paper towel and sit it under a desk lamp for a bit (half hour?) and see if that helps. Some recommend the microwave, though I've never tried that myself.
But, it could be you. Perhaps you are puffing too hard. Slow down. Take your time. There is moisture in the tobacco and water vapor is one of the by-products of combustion and if you puff too hard, moisture can collect.
Finally, get yourself some extra long pipe cleaners and if you get some gurgling run a pipe cleaner down the stem to dry it out.
