Cobalt as standard only allows 256 open files per user. This is sometimes a problem for the root user, especially if analog is running.
You can do something like this: echo "if [ "$UID" = "0" ] ; then ulimit -n 2048 ; ulimit -u 1024 ; fi" > /etc/profile.d/boost.sh chmod a+x /etc/profile.d/boost.sh When you reboot, most sessions should now have the higher values. ons, 2002-04-03 kl. 17:25 skrev Matthew Nuzum: > I've been getting a couple of interesting entries in my logwatch for the > last couple of days.
