Can you let us know, which tool or software you used to generate this output? I have one observation:

    47: OP_DATA_0x47:        push hex 47 (decimal 71) bytes on stack
    30: OP_SEQUENCE_0x30:    type tag indicating SEQUENCE, begin sigscript
    44: OP_LENGTH_0x44:      length of R + S
    02: OP_INT_0x02:         type tag INTEGER indicating length
    20: OP_LENGTH_0x20:      this is SIG R (32 Bytes)

        795C46F7860940D4:EE8A48F7B1C66C0D
    02: OP_INT_0x02:         type tag INTEGER indicating length
    20: OP_LENGTH_0x20:      this is SIG S (32 Bytes)
        CA417E99B3549CE8:0ED1DB7964DB3597
        CABF709CC614A22F:1FE7B81769775D36
    01: OP_SIGHASHALL:       this terminates the ECDSA signature (ASN1-DER structure)


The S-Value starts with CA417E99... this value in a signed int is above the allowed value. See Pieter's post at the bottom of this link. 
Values higher than one should be preceeded by "00". But before doing so, it should be checked wether it is larger than N/2. Further explanation here.
