Check size of ring buffer (#269)

There is no check if "data" fits into the ring buffer buffer.
This causes a write heap buffer overflow.
If data is too big for the ringbuffer nothing is written to the
ringbuffer and a error is logged

If the buffers are bigger than the free space in the ringbuffer, the
ringbuffer is increased by a step size set at initialization.
But there is no check if this increase was sufficient.
Fix this by using a while loop that increases the ring buffer size until
it is big enough or the buffer can not be further increased.
