[Bug 1771329] [NEW] Can't open apps due to Too many open files

[Joe Littlejohn]

Public bug reported:

Occasionally I find that I can't launch a new terminal, or can't achieve
some other desktop task. Checking journalctl I see error messages like
this:

May 15 12:12:15 jl-XPS-13-9360 terminator.desktop[11840]:
dbus.exceptions.DBusException:
org.freedesktop.DBus.Error.LimitsExceeded: Failed to determine seats of
user "1000": Too many open files


or this:

May 15 12:12:47 jl-XPS-13-9360 google-chrome.desktop[28308]:
[28308:28343:0515/121247.966786:ERROR:bus.cc(394)] Failed to connect to
the bus: Failed to determine seats of user "1000": Too many open files


At the time this happen's I'm usually running Slack, Chrome, Emacs, and a few Java apps.

I'm using Ubuntu Bionic (18.04), 4.15.0-20-generic x86_64, vanilla
gnome-shell.
