Follow the steps below：
Configuring Node(adress = 0x100) ->delete node(adress = 0x100)
Repeat the above action，I found a problem
1.Every time you configure node, it is longer than the last time.
2.Repeat more than ten times, the configuration will fail
3.I don't understand why the previous configuration can be successfully configured, and then it will fail after multiple configurations.
The last few configuration logs are as follows：

client delete serve code：
ERROR_CHECK(dsm_devkey_delete(deviceInfo[index].devkey_handle));
Server side：
node_reset();
I suspect that deleting the server node is not complete, causing such a problem.
So, can you give me some help, thank you！
