Error in eigen(a$hessian) : infinite or missing values in 'x'

Dear R-users, I'm estimating a two- dimensional state-space model using the FKF package. The resulting log likelihood function is maximized using auglag from the Alabama package. The procedure works well for a subset of my data, but if I try to use the entire data set I get the following error message. Error in eigen(a$hessian) : infinite or missing values in 'x' What's even more confusing is that if I estimate the model for a sample say data[1:200,] then there's convergence. If I estimate it for data[1:300, ] then I get the error message.
Since there is a missing or infinite value in it?
But if I estimate the model for data[201,300] it once again converges.
data[201,300] is exactly one entry (row 201, column 300). Uwe Ligges
Can anyone please enlighten me; where does this error stem from and what can I do about it? Thank you in advance. Kristian [[alternative HTML version deleted]]
