Message size get doubled in the ABAP Proxy SOAP header

Hi PI Gurus

I found something strange with regard to the message size displayed in SXI_MONITOR for SOAP messages.

The value of system parameter is

icm/HTTP/max_request_size_KB = 102400

by default, which is fine.

I just use messages with different sizes to conduct performance test on ABAP proxy. The messages whose size are 1M, 5M, 10M and 30M are all working fine. whereas when a message with 48M has been sent by the ABAP proxy, I found the message size displayed in the SXI_MONITOR is 96M rather than 48M as below. The size has been doubled here.

does anyone know why the size is displayed like this in the SOAP header? thanks
