        Should give you all the details you need live.

        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.

                What does SAR say happens just before the crash?

                top with the M command does a great job of showing memory hogs.

                      @aaronstuder Of course I know how to install it, I was just saying not everyone has it installed.

                      top 
                      

                      is the stock command included with every debian distro.

                              This is why you need sysstat, it has history.

                                  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.

                                            @scottalanmiller on my distro I have to use Shift+f to change the sort order.

                                            What is the syntax your using from the command line?
