Hello, I've had 5 servers running Ubuntu 14.04 appear to panic in the last 3 months. This usually happens within a few seconds of an update to Icinga config on either the master or the remote that the panic occurs on. For most of these I've been unable to recover the cloud server to a state where I could pull a crash dump but recently I finally was able to grab one.
I've put the most recent dump here, which occurred on a remote server when I updated some configuration on the master: http://pastebin.com/r6BBGUrJ Some searching indicated an anecdotal solution that I should set the config option const EventEngine = "poll" to avoid using epoll which is where the bug is coming from. I'm mailing the list to verify that based on the trace above that this is the issue I'm facing and that the solution is correct so we can have confidence in running the remote agent on our servers without risk of boxes get hosed randomly. - Nathan
