R help - Feb 2009 - Help on warning message from Neg. Binomial error during glm

I am using glm.nb, a ~b*c ( b is categorical and c is continuous). when I
run this model I get the warning message:

Warning messages:
1: In theta.ml(Y, mu, sum(w), w, limit = control$maxit, trace control$trace >
:
  iteration limit reached
2: In theta.ml(Y, mu, sum(w), w, limit = control$maxit, trace control$trace >
:
  iteration limit reached

What does this mean?
