Work cycle too long. Investment beginning to set while still under vacuum. Ensuring the work cycle is not too long and slurry temperature is 20 - 22ºC. 
Disturbing the flasks too soon. Leave the flasks for at least one hour.
Heating too quickly during de-wax. Do not exceed 150ºC during de-waxing.
Moulds allowed to dry out before burnout. If not burning out the same day, keep moulds wet by covering with wet sacking or plastic sheets.
