1.My quetion：JN 5169 Coordinator hang up when Roter joining the newwork.When the chip hang up ,there is no uart signal,no RF signal,and watchdog not reboot the device.When I reboot the device 2 days later, the problem disappear.
2.My envirorment:
1) SDK：JN-SW-4170 v1840
2）Coordinator：Base on JN-AN-1216-Zigbee-3-0-IoT-ControlBridge-v1011, we modify code about Uart1,RF signal handle,table size, etc.
3）the router is zigbee test tool, not real device.
3.My Operational steps：
1）Coordinator form the network
2) join other router in to the network
3) when the chip han up, there has joined 20 nodes.
4.The problem is similar to Chip JN5169 hanging in Runing
5.The Coordinator Table Size:(we want to support 30 child nodes only)
Maximun Number of Nodes 30
Mac Table Size 35
Active Neighbour Table Size 35
Address Map Table Size 35
Broadcast Transaction Table Size 9
Child Table Size 35
Discovery Neighbour Table Size 8
Nwk Fc Save Count Bit Shift 10
Route Discovery Table Size 3
Route Record Table Size 1
Routing Table Size 60
6.when problem occur, there was no any ERROR in the uart log
7.The siffer log "5169hangUpLog.cubx"was attached below,(channel 11, panid 0x22DF) line 15469 was the last packet that coordinator sended.
8.How to find the root cause of the problem and solve it？
