You probably haven't set a timeout, which means that if two threads clash neither backs off to wait for the other to finish. Use this function: <http://sqlite.org/c3ref/busy_timeout.html> to set a non-zero timeout (I suggest five seconds) after the connection is opened, and try again. If you don't have access to that API, look for an equivalent in the API you're using.
