Oversubscribing RAM Error

Oversubscribing RAM Error

This error can happen if the swap is not in place.

From the edgeLinux terminal: https://docs.antsle.com/login/

Lets check if the swap partition exists.
Does the command 'lsblk' show the the swap... one of the drives (sdb or sdd) should contain the swap partition and will look similar to this with "[SWAP}" denoting the swap partition.
sdb      8:16   1 465.8G  0 disk 
├─sdb1   8:17   1  16.1G  0 part [SWAP]
└─sdb2   8:18   1 449.6G  0 part 

If not, lets create the swap
mkswap /dev/sdb1
swapon /dev/sdb1

And does /etc/fstab have the following line 
/dev/sdb1   none    swap    sw    0 0
You can view the file with
cat /etc/fstab

If not, lets add the line to the fstab file
echo "dev/sdb1   none    swap    sw    0 0" >> /etc/fstab
