Hi All,

I’m new to ruby/rails/radiant and I can’t find any mention of this  
problem on the internet - I was hoping you might be able to help me  
solve this. This is the mongrel log file below. Thanks in advance.

\*\* Daemonized, any open files are closed. Look at log/mongrel.pid and  
log/mongrel.log for info.  
\*\* Starting Mongrel listening at 0.0.0.0:4092  
\*\* Starting Rails with production environment…

looks like something called “ShopProductAttachment” might be having a  
problem. do you have any extensions installed that are named like  
that? what happens if you disable it (move it out of vendor/extensions  
or remove the config.gem line that loads it from  
config/environment.rb) and try to start mongrel?
