Hi all,

I’m using ferret and acts\_as\_ferret on Win XP. Trying to index a  
location table with over 2,5 Mio. rows in UTF-8 I’m getting the error:

“IO Error: IO Error occured:  
Error reading the segment infos. Store listing was …”

The error occurs after some hours of running. The index file system  
looks like this after the abort:

The file \_2dqe.fs has repeatedly the same size after the error.

How can I deal with this? Will this be different on Linux?

Thanks,

Just to mention that I tried to build the index with

Location.rebuild\_index

from the scratch using Acts\_as\_ferret when the error happened.
