Then AppArmor would log that too - it usually does at least.

$ ps aux|grep virtuoso

"tol" is my account.
I noticed that Akonadi Nepomuk Feeder was constantly changing between
Indexing/Ready to index/Waiting for Nepomuk, so I closed down Akonadi
server and restored my backup of ~/.config/akonadi and ~/.local/share/akonadi.
That has saved me before when I had a power outage, and for a short while
the log was quiet after restarting Akonadi, but now it's back to crashing
every 10-20 secs.
I'm OK with rebuilding the Nepomuk db, I've been one of the lucky ones with next
to no problems with it for years, I'm just not sure of the correct approach.
Anyway, virtuoso should handle any errors more gracefully, so if there's
anything I can do to debug it, please let me know.
