I had rebooted after building nepomuk core and akonadi/kdepim from master. I had two nepomukservicestub processes and one was using 100% of one core and was at 500MB+ of RAM and rapidly increasing. I killed it and got this crash report. The crash can be reproduced sometimes. -- Backtrace: Application: Nepomuk Service Stub (nepomukservicestub), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Also the fileindexer was not running after this.
Oh!! So the filewatch service is gobbling up all the memory! I thought it was the storage service. Have you been moving a lot of files or something?
>Have you been moving a lot of files or something? Afraid not. And the builds I've been doing are excluded from the watch list
Alright. Please run the file watch service under massif. $ qdbus org.kde.nepomuk.services.nepomukfilewatch /servicecontrol shutdown $ valgrind --tool=massif nepomukservicestub "nepomukfilewatch" I need to see what is consuming all the memory.
Ping? Is this still gobbling a lot of your RAM?
Ping?
Yah, I think we can close this one - not an issue now for me. Thanks.
