error hard to digest

Dear Mahout-Users,

I run ALS on a dataset, and it works out for feature space sizes 
10,20,30. When I try to run it on a feature space size of 50, I receive 
the error below (sorry for the long mail, I wanted to include all 
output). It looks like the first iterations are fine, and it then 
breaks? It is not a memory problem, I've checked that...

Great thanks for help!

Hartwig
