Thanks for your report. Did named crash exactly once per server, without any further crashes after the service was restarted?
Do have a list of the packages that got updated in the upgrade you performed before the crashes happened? Is there a difference in the upgraded packageset between the servers where named crashes and those where it didn't? At the moment I don't really have enough elements to tell anything, but I'd try to understand if one of the upgraded packages is something named depends on (e.g. a shared library), and a if restart of the service should have been triggered by the upgrade I'm marking this report as Incomplete for now, which is our way to mark bugs for which we asked for more information. Once you provided it please change the status back to New, and we'll look at it again.
