Failed after configuring the slave multiple times

[caca1989]

Nordic team，

mesh sdk：nrf5_SDK_for_Mesh_v1.0.1_src

example: light switch

The client repeatedly configures the server multiple times. After a few configurations, there will be a failure.

If there is more configuration after the configuration fails, the program will report an error.

I modified the following places：

Pressing button 0 will delete the server, then the server will be powered on again, and the client will configure the server again,This operation is repeated multiple times.

The configuration time will increase with the number of times until the configuration fails.

Three questions：

1.Configuration time, why is it longer than the previous one?

2.Why does it fail after multiple configurations? I tried the same result 20 times.

3.After the configuration fails, the next configuration is performed. At this time, the program will error.

How will I solve such a problem and give me some help?
