Ferret DRB, can add/modify index, but not search

I’m trying to use the Ferret DRB server to avoid concurrency issues when
using multiple mongrels. I can successfully add and edit data on my
index via the DRB server, however, when I search the index, I get the
following error:

DRb::DRbConnError (DRb::DRbServerNotFound):

When I’m adding/editing data in the index, my ferret_server.log file
shows the following:

#method_missing(:add, [“Article”, {:synopsis=>“Analysis and
Projections”, :status=>1, :player_names=>"", :team_names=>"",
:publisher=>"", :title=>“Article Title”, :db_state=>0, :id=>1,
:article_published_date=>1189115220}])
#method_missing(:add, [“Article”, {:synopsis=>“Analysis and
Projections”, :status=>1, :player_names=>"", :team_names=>"",
:publisher=>"", :title=>“Article Title 1”, :db_state=>0, :id=>1,
:article_published_date=>1189115220}])
#method_missing(:add, [“Player”, {:last_name=>“Smith”,
:first_name=>“Walter”, :db_state=>0, :id=>1}])
#method_missing(:add, [“Team”, {:name=>“Kalispell HS”, :db_state=>0,
:id=>13}])


I’m running the following environment:

Linux version 2.6.16.29-xen_3.0.3.0
mongrel (1.0.1)
mongrel_cluster (1.0.2, 0.2.1)
ferret (0.11.4)
acts_as_ferret stable plugin (as of 9/7/2007)

I have no problem running this application on my local development
environment… and I had no problems running in this hosting environment
before I started using Ferret DRB.

Here are some example sorts and/or filters I’m using in my searches (not
sure if this matters to Ferret DRB or not):

Ferret::Search::SortField.new(:article_published_date, :reverse => true)

Ferret::Search::Sort.new([Ferret::Search::SortField::SCORE, date_sort])

Ferret::Search::RangeQuery.new(:article_published_date, :>= =>
UserSystem::APP_DEFAULTS[:days_for_new].days.ago.utc.to_i.to_s, :<= =>
Time.now.utc.to_i.to_s)

Ferret::Search::Sort.new([Ferret::Search::SortField.new(:article_published_date,
:reverse => true)])

Any ideas why my searches wouldn’t be working?
