Sorry, I forgot to include that I'm using SunOne Web Server 6.1 running on a Windows box. Thanks!

What is exact WebServer version? SP? We haven't seen this in current releases. If you have reproducible step, please provide them.

The Server is Sun ONE Web Server 6.1 SP7.

The steps are as follows:

1) additional document directories were created.

2) search collections were created

3) scheduled maintanence was set up

- scheduled maintanence was set to reindex the collection then

update the collection half an hour later

Apparently, I found that this was caused by a file being locked.
