   Dear R-users:

   I am fitting a model with quite many terms, and I'm having a lot of problems. 
Either I get: 


   "In mer_finalize(ans) : gr cannot be computed at initial par (65)"

   or false convergence problems, when the model is a little bit simpler. I 
attach the most complex one with "verbose=TRUE" to see if you can help me 
detectt where the problem is:

   
hatchcoltailmodel1<-lmer(nhatch~sex+mod+briventral+brithr+tlength+cond+briventral:brithr+briventral:tlength+briventral:cond+briventral:sex+briventral:mod+brithr:tlength+brithr:cond+brithr:sex+brithr:mod+tlength:cond+tlength:sex+tlength:mod+cond:sex+cond:mod+(1|site/pair)+(1|year),family=poisson,na.action=na.omit,verbose=TRUE)

   Any help will be much appreciated. Thank you very much!
