Ferret talk - Jun 2006 - Obtaining write lock when trying to write index error

Haloo.

I''ve noticed some weird behaviour while trying ferret with rails
*without* act_as_ferret plugin: when I start application under
lighttpd proxying requests to spawned fcgi processes, I see this:

  : Error occured at :703 Error: exception 6 not handled: Could not
obtain write lock when trying to write index

The same time everything goes ok with webrick. Indexing part for the
model is as simple as

def index
    index = get_index
    index << to_ferret_document    #
[RAILS_ROOT]/lib/searchable_model.rb:5:in `<<''
    index.flush
    index.optimize
    index.close
  end

def get_index
    Ferret::Index::Index.new(:path => APP::CONFIG[:store_indexes_directory],
                             :analyzer => FerretConfig::CONTENT_ANALYZER,
                             :create_if_missing => true)
end

I supposed that working with index this way would be okay  (according
to http://ferret.davebalmain.com/trac/wiki/HowTos), but it looks like
i''v missed some kind of top-secret ferret config parameter maybe or
smth., so couldnt you share that trick with me ? (Iam sure every one
knows that). Thanks.

Well, the problem was that there was an old lock file in the index
directory. The trick was to cleanup index from any locks if
application crashes or smth. :)
