On to modifying the configuration, as the original was lcnc 2.3.
Are you building linuxcnc itself from source or installing the debian package? The updated memlock limit comes from the linuxcnc debian package, not from the rtai kernel package, since it's linuxcnc that actually wants to lock memory. If you install linuxcnc.deb, it will update /etc/security/limits.conf, and then you need to log out and log back in for the new memlock limit to take effect. I think there's no real bug here, but probably a "missing documentation" issue.... -- Sebastian Kuzminsky ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
