R help - May 2010 - Gamma regression doesn't converge

When I ran a Gamma regression in SAS, the algorithm converged. When I ran it
in R, it keeps uncoverged even if I used 10000 iterations. What was wrong?
I used the following code in R:
glm(y ~ x1 x2 x3, control=glm.control(maxit=10000), data,
family=Gamma(link="log"))

What is the actual glm expression you tried to run?  Does it not
converge for just one formula or when you try different formulas/data?
