Hi all

After having some problems with Lucene trying to create more than 100,000 
subdirs under the index directory, and trying to rebuild the indexes but 
then having troubles that workspace.xml was deleted and blah blah, (try to 
avoid doing anything under pressure) I thought I would have a practise on 
my development machine.

I am using the 2.1 rar file deployed on weblogic 10.  I am using a very 
default installation, without clustering.

I stopped the server, deleted the workspaces/default/index directory and 
restarted the server.  The re-index occurs in the startup thread, so my 
weblogic has not restarted yet.

My production environment has many documents, and several systems deployed 
per server.  There will be trouble if I try to stop those other systems 
for a couple days while I re-index.

1) Am I likely to get the problem of 100K subdirs blowing up my system, 
when I get my test data reinstated (loader runs for a week)
2) Is there a way to re-index that will not cost me some body parts?

Thanks


Ross.
