After upgrading to 4.8.0 you may find that your appliance no longer has no swap space available. This causes the system to run out of memory and kerneld to start killing processes which, in turn, can cause a variety of other symptoms.

1. SSH to the appliance and login as ”toor”.

2.  Run this command:

$ vi /etc/fstab

3.  Replace  /dev/scsi/host0/bus0/target0/lun0/part3   with   /dev/sda3.
4. Save and exit the file.
5.  Either run:

$ swapon /dev/sda3

      Or reboot the machine.

Note: "swapon" is safe to run.  It is basically what the system is doing on reboot.

Note: To confirm that swap in available after running $ swapon /dev/sda3, run the following command:

$ swapon –s

If swap is available, you should see output indicating the size and device being used.  If $ swapon –s is silent (no output), then swap is not yet available. If this is the case then try running the following commands:

$ swapoff -a

$ swapon -a

$ swapon -s
