Since no one more knowledgeable is going to answer I'll take a stab at it:
What is your max_insts = ? <for the three cases?> I had this problem and I found that if the Simpoint is greater than the max_insts, max_insts is reached before the Simpoint. Further, I should presume that max_insts should be the limit/end of what you are trying to sample so Simpoint is the start of your sample and max_insts is the or greater than the end of it.
