I’m trying to understand why I received this warning message. It happened on Saturday when we had almost no traffic on the server, and it caused the service to reboot.
My understanding is that the overload should not result in crash, so one possibility is that they share a common cause. Actually, causing a reboot should be almost impossible for a user space program; it would have to cause an extreme, acute resource depletion that couldn’t be resolved by killing the process.
-Real enviroment.
-MariaDB
-Asterisk 13.38 (I know it’s deprecated, we will migrate everything to a newer server this year)
-I don’t see a os panic message, just asterisk restarted nothing else in my system

If you are using realtime database accesses may be backing up. Although there is no real traffic, you might have a burst of reregistrations.
If Asterisk terminates without logging anything, it is likely that it is either the OS that terminated it, because there was no sensible way to continue, or it requested the OS to terminate,for similar reasons. In those cases, the OS may have logged some information about the failure.
The comments about user programs not causing a reboot applied to reboots, but it seems that you didn’t have a reboot.
