xWR1843: Industrial ToolBox traffic monitor radar re-configuration issue

Part Number: AWR1843

Hi

I'm using traffic monitoring lab of industrial ToolBox  4.5.1, but I find the radar will hang when I re-configure the radar. Below are the CCS debug result I configure the configure 1 than stop the radar and re-configure with configure 2, the system hangup and I find there is no DPM_Report_DPC_STARTED to post the gMmwMssMCB.DPMstartSemHandle. But if I change the frameCfg of the configure 2 to frameCfg 5 7 40 0 200 1 0 ( only change the number of the loop to be same with configure 1 ), than it can work. 

So is there any limitation for reconfigure the radar ?

Thanks.
