Poisson distribution for large mean

Hi,

I am using poisson distribution
(boost/random/poisson_distribution.hpp), and have encountered a
problem when using a large mean. 

Let's say I'm setting up my poisson distribution with mean = MEAN, and
repicking a sequence of 1000 random numbers. If I average out these
1000 numbers, I would expect to get MEAN (or very close to it).

This works OK for mean < 745. Afterwards, no matter how large I set
the mean, the same sequence of numbers is generated, with average of 745.

Any help would be greatly appreciated!!

Thank you,
Ksenia
