WebService error -- Address is redirected

Recently, I am responsible for the maintenance of a project. Although there are some problems in this system, it is acceptable that it is not a major problem, so there has been no excessive maintenance, until Friday, the Service suddenly crashed and the problem could not be solved for a while.

WebService errors generally occur when the service cannot run, or when there are no files or the like. They are common and handled, but I cannot figure it out when I reported "redirection from this address to this address" that day? Later, I asked you a question. I don't know much about this question. I can't debug it.CodeRight!

In the debugging process, the main functions of this part of the Code are not clear, so there is no problem in simply finishing the code to be executed, later, we found that the list of interfaces was created. After the method is executed, although the call is not released, the interface is released. Therefore, this error is reported after the function is executed, this error is the memory release problem mentioned earlier in fastmm4, leading to service crash.

However, this question may be unacceptable. Does it seem too vague?
