Limit of open files mistake: set to 0
Assuming that you have physical accessibility to the equipment.
I believe you will not have the ability to repair it by starting to solitary customer.
So order on your own a Linux LiveCD (any kind of distro will certainly do, I favor Gentoo's).
Boot from it, place your neighborhood CentOS origin dividing, modify the called for documents, umount and also reboot.
That need to be it.
A choice to making use of a boot CD is to reach the grub boot food selection and also modify the bit line to add "init =/ bin/sh". With Ubuntu you require to remove "quiet" and also "splash" from your bit line also. Currently boot this changed boot alternative. You need to get unloaded right into a shell. You require to remount your origin documents system read - write making use of:
# mount -o remount,rw /
Mount any kind of added filesystems. Modify your limits.conf and also wait. Remount the filesystem read just:
# mount -o remount,ro /
Throw in a "sync" command simply to be on the secure side, after that reset the computer system. Currently you need to boot generally.
