I use Kontact (4.14.10 under Plasma5, Fedora22), and the akonadi_notes_agent always occupies around about this much memory. I have very few notes, but it seems ALL my email is also listed in a notebook. I don't want this, I'm not aware of having set it up like this, I don't seem to be able to stop it. If I select "Notes" in Kontact then its RAM usage goes up around 1.25Gb and 50% cpu usage. I haven't been able to find a solution either from the help or the IRC channel(s). Reproducible: Always Steps to Reproduce: 1. Turn on computer 2. 3.
I use KMail 4.14.2 and also observe a very high memory consumption (6 to 7 GB) of akonadi_notes_agent. I don't think that I've ever used any notes in KMail.
I have now solved this for me by deleting the notes agent as suggested here: https://www.kubuntuforums.net/showthread.php?65497-Akonadi-Notes-Agent-hogs-memory Actually, in my case, deleting the Notes agent in the kcm_akonadi GUI was not enough. Only after I have manually deleted all lines containing "notes" or "akonotes" in .config/akonadi/agentsrc and then deleting the notes agent via kcm_akonadi again, the akonadi_notes_agent is gone (for good, I hope).
