Comment (by jinmei):

 Replying to [comment:8 jelte]:
 > I have seen this one as well where I don't run Stats. It is not so much
 a timeout issue; the problem is that stats collection is a 'push' method;
 modules push their stats regularly to the Stats module. Since they expect
 the module to answer, and they do not check whether it is running, this
 results in a timeout (noone is answering). The easy fix would be to not
 expect a response. A better solution might be to make it a pull action
 ('getstats' or something, initiated by the stats collector)

 I'd actually suggest revisiting the IPC method for statistics at more
 fundamental level.  Blocking/timeout issue aside, I suspect the CC
 channel is not appropriate for exchanging statistics information due
 to scalability issues.  I assume we'd eventually (soon?) like to be
 able to have per-zone statistics, while still allowing millions of
 zones to be served.  If there's a reasonable way of using the CC
 channel to exchange all of the statistics, that's fine, but I suspect
 we need to use a different method for this purpose.
