I have had my bitcoind turned off for a couple of months and I just turned it on again (bitcoind -daemon), and it seems to be reloading the entire block chain from scratch. Shouldn't it be loading only the blocks I am missing from the last two months? Why is it starting over from the beginning? Is there any way to get it to remember the blocks it already downloaded from before?
It seems to be increasing in blocks very rapidly, so possibly it is just reading through the blocks on disk and updating its memory?
