Rails - Nov 2010 - rake aborted! getaddrinfo: Name or service not known

I''m deploying new rails applications.  Everything works well
except when it comes to the db migration:

* executing "cd /var/rails/benefits_test/releases/20101129190121 &&
/opt/ruby-enterprise-1.8.7-2010.02/bin/rake RAILS_ENV=production
db:util:migrate"
servers: ["ps-test-app1"]
[ps-test-app1] executing command
** [out :: ps-test-app1] (in
/filestore/rails/benefits_test/releases/20101129190121)
*** [err :: ps-test-app1] rake aborted!
*** [err :: ps-test-app1] getaddrinfo: Name or service not known
*** [err :: ps-test-app1]
*** [err :: ps-test-app1] (See full trace by running task with --trace)
command finished
failed: "sh -c ''cd

When I manually run it with ''--trace'' I see nothing evident:
[root@ps-test-app1 current]# rake RAILS_ENV=production db:migrate

I can ping the db with no problems and I can also telnet to the db
successfully from the app server:

[root@ps-test-app1 20101129190121]# telnet ps-test-db 3306
Trying 10.204.47.161...
Connected to ps-test-db.localdomain (10.204.47.161).
Escape character is ''^]''.

5.1.33jSD7(_*2J\rJWW.~R\[
                ot packets out of orderConnection closed by foreign
host.

I’m using the following “database.yml”:

production:
  adapter: mysql
  database: tsise_development
  username: *user*
  password: *pass*
  host: ps-test-db
  reconnect: true

Can someone help me out?

Thanks,
Franck
