So I copied the same file from an installation of another server I have on which things are running ok. I restarted but it continues to throw up those respawn messages and shared mem segmets stuff.

Also, it worked fine, I didn't change the sysctl file before, it seems silly to assume that it just changes itself out of the blue and stops working. I installed nothing, there is no source I can assume to have done so. What can I do to make this server working again?
