Issue : INIT: no more processes left in this runlevel
This is one of the issues i had for several months, i couldn't find any specific information about it and never had time to trace it in order to find a solution. But today i managed to fix it by reading many threads and articles and then tracing it from the beginning , since i'm not the only one with this problem i decided to share it.
I used CentOS 5.3 for this tutorial , but it might be still useful even if you're using a Debian based distribution.
