Description Martin Tlustos 2013-04-15 12:59:48 UTC

Kubuntu 12.10:
I was looking for a certain email across my 3 imap accounts and in my local folders. The first search worked. I didn't close the search dialogue, but typed in another search. An error message popped up. I closed the search dialogue and reopened it, and searched again. No error message, but no results displayed. i then realized that virtuoso ran high (99% cpu). 
I closed kontact. No help. 
I stopped the akonadi server. No luck, virtuoso stayed high.
I stopped nepomuk, restarted, disabled email indexing, disabled file indexing, stopped nepomuk again. No luck. Nepomuk responds very slowly.
I rebooted. Akonadi behaved well for a while, but as soon as I started kontact and clicked on an email, akonadi went wild again.

It also seems to block dolphin from working well, dolphin takes very long to start up and respond.
There is no hd activity from virtuoso-t
I can't even terminate it (neither terminate nor kill work!)

Reproducible: Didn't try

Anything that works with akonadi or nepomuk is blocked: dolphin, kontact, konqueror, akonadi-console.

Update: disabling email indexing in nepomuk and force-close virtuoso-t "resolves" the issue. But as soon as I re-enable email indexing in nepomuk, the problem starts again.

Did you have a search folder in kmail with a very high e-mail count? I had this (over 10,000 "hits") when I messed up an e-mail search.
After removing the "Last search" folder, nepomuk went silent.
(However, since then nepomuk starts several virtuoso-t instances which use ~50% of my 4GB RAM. No idea why.)

Seems resolved with Baloo. Closing.
