Comment:

 Mentioned this on IRC -- mentioning it here too so that it won't get
 forgotten.

 Roger thinks this might be related to #6472, which was fixed in 0.2.3 but
 not backported.

 If upgrading a couple nodes to 0.2.3 fixes this, that's great.

 The logs alone don't seem to tell me where the double-free is coming from:
 if you could possibly get a stack trace , that would probably help more.
