Ubuntu 14.04 crashes due to using too much memory
-
I am running Ubuntu 14.04 and my server started crashing every few hours due to memory. I increased the memory and everything was fine for awhile, but now it is crashing again. How can i find out what is hogging the memory?

topShould give you all the details you need live.

@DustinB3403 or better yet
htop -

Right now it is using very little memory (2%) . I just rebooted so I will check when there is an issue again.
-
@IRJ Why are you not running Ubuntu 16.04? Also check sysstat.
-
@aaronstuder htop might not be installed on his system.
I know it's not on me debian system.
-
apt-get -y install htop -
What does SAR say happens just before the crash?
top with the M command does a great job of showing memory hogs.
-
Is this is VPS?

He hasn't had all that much time to update.
-
@aaronstuder Of course I know how to install it, I was just saying not everyone has it installed.
topis the stock command included with every debian distro.

@DustinB3403 Does top have pretty colors and bar graphs? lol

This is why you need sysstat, it has history.
-
@IRJ is this related to this?
-
As a learning experience
VIRT is the "used amount" of memory and %MEM is obviously the "amount of total" memory.
-
Here's an older site explaining the top command if you need further details.

That's why I was asking for the sar output, it will show what was going on leading up to the crash.

But hit M to reorder the display by memory used, rather than by CPU used.
