Wakeups logs iOS 10 - ios

I have an app based on Cordova, where I have added some native code. Now many clients reports to me app crash with this log:

What is this "wakeups"? Serveces that wakeup the app when this is in background?
And if are these.. can be UIWebView?

There is a limitation of Safari, I also experienced the same pain especially on iPhone and iPad.

What is a fence-hang / handling fence / blown-fence error?

I had an iOS iPad app crash and got the following crash log from the Devices tab:
Date/Time: 2017-10-13 15:06:22 -0600

Any insight into what this error is and what causes it?
According to this Apple Developer Forums Thread, one cause of blown fence errors is due to high memory pressure.
The developer of the app in question might be able to monitor memory pressure of the app, which could be a cause for the app being terminated.

Xcode simulator not working error - could not load inserted library '/usr/lib/libignitor2.dylib' because no suitable image found

Updated my xcode this evening to 7.2.1 im running on yosemite 10.10.5
i've just started learning swift, and everytime i try to run the simulator it crashes with the error:
could not load inserted library '/usr/lib/libignitor2.dylib' because no suitable image found.
I have spent the last 4 hours searching online, there seems to be a few similar errors of inserted library missing but nothing that i can see that helps with this error. The full code can be seen below.

You could try
sudo update_dyld_shared_cache -force
I'm trying to fix my beta but it appears to be trying to get after an update and this is the solution I"m working with. If it fails you can try

iOS 7 crashes when opening Ionic/Cordova Tutorial App

My iPad crashed a few times when opening this Todo App. It freezes and I have to do a hard reboot, every time. I don't know yet how to reproduce it, but it has happened right after opening the app (probably when opening it again right after closing it).
Here's the device log from Xcode:

I have no idea how to debug that. Any help will be greatly appreciated!
EDIT
The iPad crashed once again when running the same sample app from Xcode. It trashed on Cordova's splashscren.

Cordova 2.6 / 2.7 iOS app timing out

I have an app that I've been running successfully for the best part of a year built with Cordova 2.1. Recently I decided to start a new build with 2.6 and it runs fine on iOS 5, but not iOS 6. Went through the crash logs which all point to "[app] failed to launch in time". Unhelpfully it also has 'backtrace not available'.
To try to pin down what I'm doing wrong, I basically started from scratch - create a default Cordova app. However when I run that - just the very basic app that is created when you create a new project from the command line - it also has the same error. Get the splash screen, stalls and then crashes with the failed to launch in time error.
The apps run fine in the simulator, but when I run them on a device from Xcode or archive them and install them, nothin'.
Im using Cordova 2.7.0, Xcode 4.6.2 on OSX 10.7.5. If it helps, one of the full crash logs is below...

iOS App crashes under 3.1.3 when compiled with LLVM2

I have an iOS app with the following (selected) build settings in XCode 4.0.1:
Architecture = Standard (armv6 armv7)
Base SDK = Latest iOS (iOS 4.3)
iOS Deployment Target = iOS3.1
Other linker flags = -lxml2 -weak-library /usr/lib/libSystem.B.dylib
Under Targets/Build Phases, I have libSystem.B.dylib as Optional (Link Binary With Libraries).
On a 1st gen iPod Touch, I'm getting the following results:
Debug Build, C/C++ Compiler Version = LLVM Compiler 2.0, all OK
Ad Hoc Release Build, C/C++ Compiler Version = GCC 4.2, all OK
Ad Hoc Release Build, C/C++ Compiler Version = LLVM GCC 4.2, all OK
Ad Hoc Release Build, C/C++ Compiler Version = LLVM Compiler 2.0, crash a few seconds after starting.
In case 4., the crash report looks like this:

etc.
The crash happens after a number of routines in my code have executed (I can see console output confirming it).
Does anyone have any ideas what would cause this to work under GCC4.2, but crash under LLVM2?
It's just a wild guess, but there was a compiler bug recently in llvm2 that made our app crash the same way. It only happened in release mode with full optimization and only on older devices (probably a specific processor). We switched back to gcc and everything was fine again. Apple updated their compiler in mean time which "fixes bugs for iOS", but we didn't test it yet.
The same problem still occurs with XCode 4.2 (4D199) when code is generated with Apple LLVM compiler 3.0.
AdHoc App works fine on iOS5 on simulator, iPad1 and iPhone4.
Same AdHoc code crashes on iPhone 3 and iPod3 on iOS 4.2.1 (8C148).
Debug code works fine on all platforms.
When the problem occurs the console log shows the following:
SpringBoard[25] <Warning>: Received memory warning. Level=1
MobileSafari[283] <Warning>: Received memory warning. Level=1
configd[23] <Notice>: jetsam: kernel memory event (93), free: 241, active: 1109, inactive: 760, purgeable: 0, wired: 7878

SpringBoard[25] <Warning>: Application 'MyApp' exited abnormally with signal 9: Killed
Peak memory usage of the App is a couple Mb. The debug code never reaches a critical memory limit.
The problem disappears when either:
Optimization Level for AdHoc is set to None (-O0)
The compiler is changed to LLVM GCC 4.2
So far, extensive analyzes of code and memory management have not provided an indication what might be causing this. It seems like a compiler bug...
