The reason could be the sample itself, try

xtlogit, fe
xtlogit if e(sample), re

Or the quadrature, try
xtlogit, re quad(8)

R.

Dear Stata Listers,
I am using STATA/SE 9.2 and running a simple random
effect logit model with a combination of discrete and
continuous independent variables. The dependent and
discrete independent variables are all dichotomous. 

When I run it, after several iterations it says "not
concave" and keeps iterate with no results. Can
anybody provide any suggestions to make it work.
Thanks. 
Pallab
