GWT Logging

Hello,

I've recently been having some native app crashes with my company's app on iOS devices. It seems to be a memory allocation issue, given the crash log says:

Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Subtype: KERN_INVALID_ADDRESS at 0xbbadbeef

I was doing some testing, and I found that we do a lot of logging to the console, which is great when we're using chrome or a chromium based desktop app that we have to test with, but I was wondering if this would be persisted on an iPad running a native app which runs our GWT app by default or where I would be able to check this setting, as I was not the one who set this up. Our app has a synchonisation process which can upload and download a relatively large amount of data, and all of this is logged as it happens, with the exception of raw data for images. I am wondering whether this, in combination with the images we are occasionally sending, is enough to put us over the limit that iOS allows individual apps.

I am sure that this is not an issue with the native app. This is a relatively recent issue, while the native app has been running without changes for a long time, and it isn't an issue with a new version of iOS on the device either.

Have any of you seen this error happen in your own apps and was there an issue that you found that might be of some help to me trying to diagnose my own issue? I'd appreciate any help or answers that can be offered.

Thanks,

James
