OS: Ubuntu 15.10
Linux Kernel: 4.2.0-25-generic
Running MongoDB gets the CPU consumption high, with the culprit being kswapd0 process
Fix:
add this to /etc/rc.local:
echo madvise > /sys/kernel/mm/transparent_hugepage/enabled
As per this URL: https://www.reddit.com/r/chrubuntu/comments/3ru04q/help_kernel_process_kswapd0_randomly_consuming/
The next attempt:
echo 3 > /proc/sys/vm/drop_caches
One more attempt:
worked around by commenting out line 2 in /lib/udev/
And the last attempt really worked:
Just updated to the last kernel update on ubuntu 15.10 :-)
