bread is really short?

With our machine (not panasonic) it depends on how much warm liquid is being added because of the change in air temperature.
In the winter I add a whole measuring cup of very hot and half of cold and in the summer a whole cup of cold and half of just warm.
If the machine is by the fridge, it might be getting extra heat from there too as the heat exchanger thingummy must work harder in the warmer weather.

If you've tried different flour and different yeasts then I'd agree with culpepper and say it's the temperature, especially if it's only happened over the last week when the weather has been warmer.
