I found these application error messages in our SPS 2003 web server event log.

1) "The content index server cannot update or access its database because
sessions are unavailable. Increase the system resource usage setting for the
search service. If the problem persists, stop and restart the search service."
2) "The content index cannot be loaded. The content index metadata cannot be
read."
3) "Index propagation to search server<server name IP address> was not accepted.
The content index metadata cannot be read. "

What will need to be done to fix these errors? Is there any documentation
pertaining to these errors to help fix them?
