My IOC is built but I have trouble with xspress3config, note that my Xspress3 chassis has more than 4 channels.

I changed the Y_SIZE (max_channels)  in xspress3/iocs/xspress3IOC/iocBoot/iocxspress3-4Channel/st.cmd to 6

xspress3Config("XSP3", "6", "1", "192.168.0.1", "16384", 16384, "4096", 0, 0, 1, 0)

but I get messages from xsp3_config that I don't understand

xspress3_config: Card 0

xspress3_config: host10GigeIPaddress 192.168.0.65

xspress3_config: femIPaddress 192.168.0.2

xspress3_config: fem10GigeIPaddress 192.168.0.66

xspress3_config: femMACaddress 2.0.0.0.0.0

xspress3_config: 10GigePort 30124

xspress3_config: nchan 4

xspress3_config: scope module name xsp3_scope0

xsp3_config: Configuring node on path 0 name=192.168.0.2

then later

xsp3_config: Configuration found 6 chans_per_card on path 0

xsp3_set_num_chan: Max number of channels on path 0 is set to 6

xsp3_set_num_chan: Number of channels on path 0 is set as 4

This error appears to come from the Quantum supplied library (?)

I don't know what it is trying to tell me
