[Building Sakai] Issue with Search tool "Failed to delete documents"

[Earle Nietzel]

The Search tool is currently not working in our sakai 2.6.0 instance and 
it keeps generating these messages in the log file:

We have 2 nodes in our cluster with the following properties:

search.enable = true
localIndexBase at org.sakaiproject.search.api.JournalSettings=${sakai.home}/indexwork
sharedJournalBase at org.sakaiproject.search.api.JournalSettings=/mnt/san/searchjournal

I tried "Rebuilding Whole Index" thinking maybe that this would remove the 
existing index's and rebuild from scratch but that did not seem to work.

Ideas?
