iOS KCSHttpRequest Crash

I have experience four crashes on an iPad Air 2 with iOS 10 recently. A restart appeared to eliminate crashes, but I pulled the crash logs and all four showed an issue with “KCSHttpRequest” as shown below. The iPad is attempting to download a file from Kinvey via a Query in general. After thousands of calls to Kinvey, I haven't experienced any issues in months. Except when this one particular iPad crashed four times over two days from the same issue.
