Hi,

I keep getting locking errors when updating my index which puzzles me  
since only one process is supposed to be accessing the index at a  
time (at least in development mode).

I'm using Ferret with Rails (NOT acts_as_ferret, though) and employed  
an observer to add a new document to the index when a new  
ActiveRecord is created. I'm not sure if this has any impact on the  
concurrency issues, but I thought I mention it.

Find attached the verbatim error message and the relevant part of the  
stack trace.

Any ideas?

Cheers,
Andreas
