Can anyone tell me about this error?

Error: The job for model 'LDE_Model_1' exited abnormally with the error message: Expected covariance matrix is not positive-definite in row 0.

Odd part: I ran the model more than once. This error came up with one data set, but not another. Seems like different observed data should not change the expected covariance matrix.
