[R] "False convergence" in LME

I tried to use LME (on a fairly large dataset, so I am not including it), and I got this error message:

Error in lme.formula(formula(paste(c(toString(TargetName), "as.factor(nodeInd)"),  : 
  nlminb problem, convergence error code = 1
  message = false convergence (8)

Is there any way to get more information or to get the potentially wrong estimates from LME?

(Also, the page in the NLMINB documentation,  http://netlib.bell-labs.com/cm/cs/cstr/153.pdf, has errors in it, which makes it harder to check on what is happening.)

Thank you in advance!
