In Logos 5.0a on OS X 10.8.2, used command rebuild index that crashed during library indexing:
5582.Indexer.log.zip
Suspect resource NKJV.logos4 (LLS:1.0.30) encountered crash.
After indexer crashed, instead of retrying indexer, choose follow-up to reply => http://community.logos.com/forums/p/60486/431073.aspx#431073 so kept two database files: Users and License Manager while moving other Data and Documents to a different disk partition. Launched Logos 5.0a to work offline, then used scan command. Restarted Logos 5.0a to work offline so scan could discover, copy, and index resources, which completed in 11 hours. Restarted Logos 5.0a to work online, which is currently downloading Documents. The resource check for updates found 0 resources to download.
Logos 5.0a took a bit over 11 hours to completely index resources while Logos 4.6a SR-3 took 25 hours. Thankful for Logos 5.0a indexing speed improvement.
Keep Smiling [:)]
