I just put the server back up either way - I was curious if taking it down would remove some response time alerts I'm getting from the AppFirst agent I put on there but nope, still getting them. Must be something else. Maybe related to the server having been online pretty much since the day we got it without a single reboot (yay Linux! 409 days uptime and counting, I'd sort of feel bad having it rebooted ..)
I'll have to look at some other stuff sometime. Nothing actually seems impacted, might just be a false alert from the monitoring agent.
