Does this mean my dataset has too few observations?

I ran a GLM regression with 5 indepedent variables. My dataset contains 238 observations and I got error message like this:
Warning: Regression design matrix is rank deficient to within machine precision. > In TermsRegression>TermsRegression.checkDesignRank at 98 In GeneralizedLinearModel>GeneralizedLinearModel.fit at 1174 In fitglm at 133
Does this mean I have too few observations? Because if I have 347 observations, it runs fine without any complaints.

My guess is that there is something strange about Observation #238. Check it to see that all the data in it are valid.

My point is that there is something about the added observation that is crashing your design matrix. I would check to see that all the data in that observation are valid.
