None of the code in that file seems to be even remotely related to Vapor. That includes the crash: one of your classes, not necessarily this one, has a deinit which illegally captured self – for example in a DispatchQueue.async closure that the code is seemingly infested with.

This is the result of a misuse of Dispatch causing an object to be resurrected during its deinit; it has nothing to do with Vapor.

@shenfu1991 It's very strange that your code crashes only once a month. Due to your illiterate use of the GCD, it should crash every few minutes.

@mkll This is indeed very strange. It doesn't crash every month, and I'm not sure when it crashes. I have encountered this several times. I will fix the error in GCD and observe again. Thank you to the individuals mentioned above for pointing it out.

Actually, this class should never be destroyed because I haven't discarded it. It is an infinite loop task.
