I created a parser and split the entire chain into pieces.

When inserting them into a database, to my surprise there were 187 blocks with the same hashes, so initially I thought there was something wrong with what I was doing, but after debugging, I found duplicates inside the blockchain.

I only investigated one block with the hash: 00000000000000000002927103A1BC8426DEFE05CFFA40BE468072B984C8876B.

I found the same block in two different .dat files: blk03361.dat, blk03363.dat.
I know for sure that the two blocks are identical because I split both dat files into blocks and compared the hashes:

sha256sum 1/1_part_65.bin
d81340e3e1c1759e4b78dc1cd531230b55d1828fd14ed0f9ba8cd9269a7ee322  1/1_part_65.bin
sha256sum 3/3_part_77.bin
d81340e3e1c1759e4b78dc1cd531230b55d1828fd14ed0f9ba8cd9269a7ee322  3/3_part_77.bin

The first one has the height 772553 and the second 772776.
Is this normal?
