Workaround

1. Should this happen, SSH into the CLI Console and execute "debug disk" command. Ensure there is sufficient storage available.

If there are highly utilized partitions, contact Support to assist in freeing up the disk space.

2. If there is sufficient storage available, the problem is likely due to a shortage of memory. In this case, the software update could be scheduled to a time where load is lower on the appliance. Another option is to reboot the SSL Visibility appliance to free up memory and retry the software update.
