Cannot read dm code when reuse

[darouwan]

I use the libdmt with pylibdmtx into my python program, and this program will process dm code every day. Recently I find it cannot read datamatrix after running for several days. But if I test the same image or restart the program, it works well again. Anyone meet the similar problem?
