st: Cox Regression - flat region resulting in a missing likelihood

Dear all,
I set my data stset and then I tried to run a stcox and got the following
error message " flat region resulting in a missing likelihood r(430)";
There should be reasonable variation in my depended variable, which is
the time measure in months until death and my data is
non- censored, meaning every observation unit experienced the "event".
I would be greatful for some input.
Thank you in advance,
Best Theresa
