st: not concave Poisson estimation

Dear statalist:
I have a panel with 5400 pair of countries and 43 years. I am trying
to estimate a Poisson model but when I assume random effects and
specify:
xtreg depvar indepvars i.exporter i.importer i.year, re
Stata keeps iterating the function over the same values during hours
and never converge
How can I solve this?
Thanks in advance
