Dear All,

I am stuck with one issue on which not getting any solution, that is the security gateways are restarting randomly. Not getting any logs in /var/log/messages or in boot_log.elg. Also, I did open a ticket with the support team, as per them firmware has to be upgraded. We have performed that activity but the issue is still the same. We have 1490 appliance in our network on which R77.20.75 is running.
Kindly suggest.
