Anybody ever seen bad DNS entries cause crashes in compiled Linux applications (specifically on the Red Hat side of things)? My guess at the moment is somehow these DNS failures are causing a resource limitation.

It doesn't make any sense from an application point of view, since !nagioscore sees down hosts all the time. These is not a beta, this is in a version that came out in 2016 and I'd guess 80% of our customers are using. There's a better chance that we are living in a simulation than that this is an application issue. Of course, that doesn't mean it's not an application issue.
