ADDITIONAL INFORMATION

I can't open *anything* in the K menu or from the task manager. I'm getting a "Resource error (fork failure): Cannot allocate memory" error for everything, see attachment. Also, none of my desktop icons are viewable.

I have 16 gigs of memory total, and have been running Kubuntu for a year without any real problems. I don't know what update brought on this behavior? Running free -h shows I have 9.1Gi left, so I don't know what is going on.

The only way I was able to even open Firefox to file this bug report was krunner. So far, I've been able to open most things through it, or typing into konsole once I opened that through krunner, but this is a huge inconvenience.

I don't appear to have a memory leak, so I don't think the suggested bug that this was listed as a clone is accurate. I'm reopening this ticket.

William, my memory usage also looks normal when bug 469445 occurs.  Did you try deleting the [ScreenMapping] section in .config/plasma-org.kde.plasma.desktop-appletsrc as described in that bug?
