>From what you submit it looks like data->state.conn_cache is NULL (or pointing to recently freed memory). I would recommend that you run your application under valgrind and try to trigger the error and see what valgrind finds. If this is a use after free, valgrind will point out where it was freed which would give a better indication on where the problem lies.
