We've been getting a crash on an app under development which is producing logs with the message: "45001 wakeups over the last 174 seconds (258 wakeups per second average), exceeding limit of 150 wakeups per second over 300 seconds".We have narrowed down the cause of our crash to some temporary debug code that was firing more-than-usual numbers of analytics events. Our analytics system uses AWS Kinesis Firehose: https://github.com/aws-amplify/aws-sdk-ios/tree/master/AWSKinesisObviously we can fix by disabling the debug code, but we'd like to have a better understanding of the problem so that we can make our code (or the AWS code) more robust. Additionally, we know of at least one end user that has experienced similar issues on a released title and we were unable to help them get our product working on their device - I now suspect their problems may have been related.Basically, I don't know what a wakeup is in this context, so I therefore don't understand how to go about controlling the number that we trigger. It must refer to something other than ordinary multi-threading activity, because 150 thread switches per second is such a low limit that it would effectively prohibit multi-threading (the limit is only 2.5 per frame at 60fps!). I also don't think it can refer to background execution because our app doesn't do any background execution and the crashes are not associated with multitasking at all.Can anyone tell me what a wakeup is in this context? And maybe give me advice to help me find the code that is causing them?
