Little variability in outcome; "pwrssUpdate did not converge"

I have a dichotomous outcome (child mortality) with a very high mean
(0.9946) in a large dataset (3.5m).

I thought maybe the problem still is complete separation and I'm just being
too timid with the blme prior.

Oddly (maybe not), the only model where I do get convergence is one where I
accidentally mis-specified my sample, so my outcome was censored (hence the
mean but not the intercept was lower). I'm attaching the model.

The misspecified model? Maybe you should be doing something else, such as 
bivariate logistic (dropping extra offspring) or marginal models? If you 
are interested just in familial aggregation, you can do the conditional 
analysis using just the ~18000 odd families with one or more events, 
using the other families just to estimate offsets.

A few random thoughts ;)
