Description Ilya Hegai 2013-03-01 11:26:05 UTC 
akonadi handling ~/.config/akonadi/agent_config_akonadi_nepomuk_feeder_changes.dat causes heavy IO load which leads to ~3Gb per day written according to iotop (I was forced to use anything-sync-daemon to link this dir to tmpfs), almost each kmail operation ended with that file is beeing rewritten (and judging by iotop completely rewritten)
As SSD user I've been worrying about it not because of SSD resource (which is quite decent nowadays) but because of disk is getting pretty warm (just like HDD under constant heavy load)

btw, nepomuk itself is disabled on my system

I've been receiving just about 50 e-mails per day

Reproducible: Always

I don´t think this is fixed, but it mine might be a different bug:

Since 4.11, change recording is disabled in the Nepomuk Feeder agent, so it should not generate any more IO (related to this particular report).
