--- Comment #11 from Tomas Kuchta <tomas.kuchta@xxxxxxxxx> ---
Today, I created another user with not encrypted home. When logged in, I did
not observe any systemd-coredump processes.

I verified that login-into KDE session with encrypted home causes the high
load.

To reproduce this bug please follow this general procedure:
-----------------------------------------------------------
1. Install Leap 42.3 + update it (update is not essential to observe the bug)
2. Create a user with encrypted home directory (I use 25GB home size for the
user)
3. Go to tty2 (Ctrl+Alt+F2) login as the user with encrypted home (this is
essential - otherwise the user will not be able to start KDE session)
4. Go to tty7 (graphical session - Ctrl+Alt+F7) and login into encrypted user's
KDE session
5. Observe high load caused by systemd-coredump processes (one for every
core/thread)

I sincerely regret that I did not notice the encrypted home dependency sooner.
It would have helped debug it.

Thank you, Tomas
