SDK 2.0 Bug?? TCP server_UART proj

[cychen]

we use UART_TCP demo on SDK 2.0 .
soft Ap mode one pc client send data and recv data is ok. but one pc keep client link, now we use other pc connet to server .
this time one pc cannot recv data.
other pc can recv data.
after some time esp8266 will reboot.
I find my user.bin cannot fine 0x4000df64
this addr(0x4000df64) maybe boot_v1.6.bin.
My code bin addr @0x01000
Err code:
Fatal exception 29(StoreProhibitedCause):
epc1=0x4000df64, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

The UART-TCP demo only support 1 connection, if you look into the source code you will find that...
