Run into a very strange question, micro service call, between the chaos, the specific situation is like this:

Step 1, the first request, the function A: [] entrance - & gt; [A] service - & gt; [B] services; Return to normal
Step 2, then the request, function B: [] entrance - & gt; [A] service - & gt; [service] C - & gt; [B] services; Return to normal

Then continue to:
Step 3, again request, function A: [] entrance - & gt; [A] service - & gt; [B] services; An error occurred

Inspection found that because after step 2, service [A] the [B] service, did not correct the service [B], but mistakenly go into service [C],

For help: what is this excuse me, how to solve?
