What does the warning message "prediction from a rank-deficient fit" mean in logistic regression




I got some warning message while using logistic regression as:

Does this message signify that since prob values are being calculated the predictions might not be that accurate?
How do I take care of this warning,is there a way to create ranks instead of prob while using glm in R

Error 'prediction from a rank-deficient fit may be misleading' in glm in R


it seems that you use too many predictors in the formula of glm for the data you gave.
