glm: NA/NaN/Inf in foreign function call

Dear all, I am running the glm function (family: Poisson) in R and most of the time it works fine. But sometimes, with large data sets, I get the following error message: Error: NA/NaN/Inf in foreign function call (arg 1) What puzzles me most about this is the fact that there are no missing values in my vectors at all- so where do the missing values come from? Could this be related to the size of the vectors I use?
Try using control = list(trace = TRUE) in your call to glm to see what the progress of the IRLS algorithm is.
