Application crashing showing the following crash which occured on sqlite prepare statement

I am downloading data in the background and the size of the data is very large so its taking around 25-40 minutes to download all the data. But I am facing very strange problem that my application crashes and the crash is very occasional and it cannot be detected, what may cause this crash. But my crash point shows that the crash is on the sqlite prepare statement
