High Swap Utilization and CPU Utilization on OrangePi PC

[Avinash Ga]

Hi,

 

I am running same distributed processes on my RaspberryPI Model 2B running Raspbian Jessie and two OrangePI PC's running Armbian 5.05. Though i have enough ram available i found that there is high SWAP utilization on my OrangePI PC's. Also one CPU will be always 100% in OrangePI PC's.

 

I have swappiness = 1 for both OrangePI PC's and Raspberry PI.

ulimit -l = unlimited for RaspBerryPi and

ulimit -l = 64 for OrangePI PC's.

 

 

Attached is the screenshot:-

From left:- (1) RaspBerryPi. (2) OrangePi PC, (3) OrangePi PC.

 

How can i limit the swap usage and high CPU for OrangePI PC?

 

Regards,

Please have a look at https://github.com/igorpecovnik/lib/issues/219  for possible workarounds and solutions. Feedback welcomed.

I tried this

 

sysctl.conf:

vm.swappiness=0 

vm.min_free_kbytes=0
 

fstab:

#/var/swap none swap sw 0 0 
then "echo 3 > /proc/sys/vm/drop_caches" 

 

But now its randomly killing the processes.
