Subject: Re: Writing to ferret index from multiple processes

I'm not to sure about this one. Are you by any chance explicitely
deleting the lock files when your app starts up? I've seen a few
people do that. The only way I can see doc numbers getting out of
order is if you delete the lock files. Any chance I could look at more
of your code? Is this for RForum? Perhaps I could check it out of svn.
Anyway, I hope I can help you out with this.

Dave

PS: If you are interested you should join the Ferret mailing list. You
seem to be doing some more advanced stuff judging from the bugs you're
finding. ;-)
