Does memory/CPU useage increase dramatically or are there any other symptoms of where it is choking...? What DB is it updating? What does the database tell you is happening when it starts choking? What do debug messages tell you wrt finding the bottleneck? Does it happen always no matter what start point is used? Are you using recursive functions?
