Compressor melted hole in 5+ year old defrost drain pan, is compressor overheating a possible concern
No it is not normal, if your condensing coils are exposed clean them a high temp on the condenser can cause this by itself, if there is a fan make sure it s turning I once found a dead mouse stopping the fan from turning but it is usually dust On the coils outside the box (under the fridge for the ones that have fans). There are other things that can cause this but I would check the things you can first.
