I can reproduce this issue; I can't see how the resolvability of the hostname could influence anything

The stacktrace seems to point to a locking problem... do you have more info on the configuration ?

I'm not sure about the link between the resolvability of the hostname and the issue.

This server had several nodes to manage then I'd added a new node which came from vagrant on my own machine. This node could contact the server but its hostname was not known into the server. It's the only obvious difference I've seen between this node and the others. It could be wrong.

That error seems to also have been reported by dnns:

16:53 < dnns> i deleted a node from rudder (2.5 that is)
16:54 < dnns> and it gave an error
16:54 < dnns> but.. the node is deleted
16:55 < fanf> dnns: partial success ?
16:55 < dnns> i don't know, the node is deleted, but there was an error
16:55 < fanf> dnns: more seriously, did you keep the error ?
16:56 < dnns> no but the error gave no info at all
16:56 < fanf> :/
17:04 < Vince_MacBuche> There is nothing in /var/log/rudder/webapp/2013_05_23.webapp.log which could be 
                        linked to that error ?
17:07 < dnns> no can't find any
17:16 < ncharles_> dnns: is it like http://www.rudder-project.org/redmine/issues/3420 ?
17:17 < dnns> yes
17:18 < dnns> but i can re-generate rules still
17:20 < ncharles_> so more like http://www.rudder-project.org/redmine/issues/3517 ?
17:34 < dnns> ncharles_: yes!
