From what I could find
(http://lucene.apache.org/java/docs/fileformats.html) Lucene uses files
in the directory determined by java.io.tmpdir for locking on the index
files. Are the two instances sharing this directory? If not, that's a
problem.

I haven't got additional information on the search-index sharing
question, but to avoid duplicate weblog update pings sent by both
hosts, you will want to set *pings.queueProcessingIntervalMins=0* on
one of them. There should be db-based synchronization for all of the
periodic tasks to better support clustering, but there isn't currently.

We have two instances of Roller running, backed by the same database,

just wanted to double check that this should be fine, no gotchas with
file contention etc? I'm particularly curious about the Lucene search
index directory, is it going to be just fine when shared across
multiple
running instances who may try to add to the index at the same time?
I don't know much about the inner workings of Lucene, but that
certainly sounds like a problem.
Any Lucene experts out there?
