Ubuntu

what is (sd-pam)?

Asked by LEGOManiac

I was playing minecraft (locally), which rather suddenly became very intermittent, as though the CPU was servicing interrupts every few seconds. I started "top" to see if there was some process chewing up CPU cycles and I found, under "command", the entry
"(sd-pam)" - including the parenthesis.

That strikes me as a very odd (and probably invalid?) command name and given that I have never seen it before this intermittent operation of minecraft, I'm wondering if it has any relationship?

Incidentally, I've rebooted and "(sd-pam)" is still there. The computer's performance, however, is back to normal, but I'm still curious about what (sd-pam) actually is.

You could try Oracle Java:

sudo apt-add-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Then try the game.

Sorry, I may have rambled too much in my original question. I only mentioned minecraft because it was what prompted me to use 'top'.

My real question was what is (sd-pam). Do the parenthesis signify anything. I did a quick google search and found someone else who was asking about it, but none of the respondents knew what it was.

This isn't really a problem, just me trying to learn something and puzzled by the appearance of parenthesis in a command name.
