> I found that in *FilePageStore#read(long, java.nio.ByteBuffer, boolean)* there may be a situation that we allocated the page without writing it to disk, tried to read it and instead of an error, we simply write an empty page to the buffer.
> It is necessary to understand better the reason for this behavior and either comment on this moment or redo it.
