Crucible shutdown during full index

[holly_stites_veeva]

We had a null pointer exception the other day in Crucible which seemed to indicate a corrupt index.  We cleared the cache directory and restarted Crucible which launched a full scan/index.   After about 8 hours scanning the largest repo, there's a shutdown request in the log.  What would be causing a shutdown during the scan?  We've restarted twice and the same thing happens.  After about 8 hours, it shuts down.  Please help.

There are few ways to stop FishEye: one can use stop.sh script, use UI (Admin / System Settings / Shutdown) or send TERM signal to the JVM.  I'd suggest enabling Debug mode on (Admin / Server / Turn Debug on) so you may find more details what is the source of this shutdown request.
