What you propose sounds acceptable. In the meantime I need to be careful about reloading nagios :). Once I get it in that state, I have to disable use_retained_scheduling_info and then do a full restart.<div class="gmail_extra"> <div class="gmail_quote">On Fri, Dec 14, 2012 at 3:41 AM, Andreas Ericsson <<a href="mailto:ae@op5.se" target="_blank">ae@op5.se</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div class="im">On 12/14/2012 05:13 AM, Mark Keisler wrote: > I think I found the issue.

I'll have to add a check for it in 4.x. Since we keep workers between reloads, the same thing can easily happen there. That means we'll reschedule all checks like normal when we're starting, but if a check result comes in when a new check is already scheduled, we'll remove the old event and reschedule a new one according to the retry interval. I'd suggest doing something similar in the 3.4.x branch, but I'm not sure I can commit to that one without doing a new svn clone, and that takes at least a day. Mark; Would that be acceptable to you?
