Rails Migration Hangs

I’m running a migration on my production system. I’m trying to add two
columns to the picture table. When I run the migration I see this output

== 35 Version111: migrating

– dei_add_column(:pictures, :created_by, :integer, {:default=>1,

and then nothing more, it just hangs there forever?!?

Any ideas on how to debug this, has anyone encountered this problem
