Releationship between WatchDogTermination and OOM

[echives]

Our team wants to monitor OOM recently, and i wonder if we can use Sentry to achieve that. After my test with Sentry WatchDogTermination, i have the following questions, can someone help me out🙏🏻

1. The difference between WatchDogTermination and OOM
2. I wrote some OOM codes and found that OOM does not necessarily trigger the WatchDogTermination report. What is the reason? test code like this DispatchQueue.global().async { var a = [Int]() while true { a.append(1) } }

thanks

Hello @echives, here are the docs regarding WatchDogTermination (WDT).

1. In summary every OOM should trigger a WDT, but not every WDT is an OOM.
   Right now, the only type of WDT we try do detect is OOM.

2. Did you run your code on a simulator or a device? Did you re-open the app after it was terminated in order to send the WDT report?
