It is. We have an issue with a server where it will take services offline when we have too many open connections to it. Some of the connections are days old. So when the services go down, we have to close those open connections that have been sitting around for days, then the services come back up . Not a big deal, we have a pair of these servers, and usually only one of them goes down at a time. It was fixed this morning before I tried to go back to bed.
The real issue is when I get woken up by something like this it takes me a while to fall back asleep.
Lucky I am only on call once every three weeks. Though they didn't call last night. I saw the e-mail alert before they called, because I was already awake.
