This is perfectly normal for bottle conditioned beer which relies on the yeast to ferment the priming sugar and produce gas. The sediment is the result of the yeast settling out of suspension after the secondary fermentation has finished.
The layer of sediment is typically 1/8 inch (3 mm).
A thick layer of sediment may indicate that the beer was bottled too early (i.e. before the primary fermentation was finished). It may also be the result of accidentally siphoning over some of the sediment from the bottom of the fermenter. Care should be taken to avoid siphoning any of the sediment from the fermenter during the bottling / barrelling stage. Leaving beer on a thick layer of sediment can result in off flavours developing during storage
