I have longer training runs for my models which can go beyond 24 hr, what I am seeing that my training runs are getting stopped after just running for 16-17hrs, this has been happening with me for 3 times straight leading to failing training runs. Please look into it, as we are paying $50 for the compute units, also if there is something like limited runtime rule in colab I have no idea, it would be great if one can point me to it.
