This suggests that Openfire cannot read a file named indexprops.xml that should have been created by Openfire earlier. Perhaps your instance got corrupted?

Does your log contain something like this?

Lucene index directory '{}' does not exist, but cannot be created!

If so, then you might be suffering from a file permission issue that you’ll need to manually correct.

As a last resort, you can try:

  • shutting Openfire down
  • make a backup of the Openfire installation directory
  • remove from the Openfire installation directory a sub-directory named monitoring
  • start Openfire
