Details

Description:
Using the ulimit -Hn or ulimit -Sn commands, from within gnome-terminal the result is always 256. In other terminals (xterm and urxvt tested) the result is the normal system limit of 4096. Launching xterm from within a gnome-terminal ends up with xterm inheriting the the 256 low limit. Launching gnome-terminal from within a xterm ends up with gnome-terminal not inherenting the higher limit, and instead ending up with the low 256 limit again.

This low 256 ulimit is blocking some apps from being able to be launched from within gnome-terminal.

Additional info:
gnome-terminal 3.16.2-1
This task depends upon

Another detail. Attempting to modify the limit fails.

$ ulimit -n 4096
bash: ulimit: open files: cannot modify limit: Operation not permitted

The ulimit command is not even working in gnome-terminal. It throws an error.

bash: ulimit: open files: cannot modify limit: Operation not permitted

This is not caused by a limit higher then the global setting. Attempting to set above the global setting (from a different terminal app) returns this error.

bash: ulimit: open files: cannot modify limit: Invalid argument

Fine for me using GNOME (soft 1024, hard 4096).

The FD limit is inherited from dbus-daemon. Check what launches dbus-daemon for your session.

I am reading that dbus-daemon is a dependency of systemd. ps aux shows that it is running.

/usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation
as user dbus

Im using openbox as a WM.

Wrong daemon. Look for one running as your user.

After latest system upgrade (with new systemd dbus), gnome-terminal stopped working completely. Now I get this error.

$ gnome-terminal
Error constructing proxy for org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling StartServiceByName for org.gnome.Terminal: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.gnome.Terminal exited with status 1
