John Plevyak updated TS-431:
----------------------------
Fix Version/s: 2.3.0
(was: 2.1.3)
Component/s: Clustering
Moving this to 2.3 as clustering hasn't been used in production for many years
so unless someone who wants to deploy it wants to take on hardening it right
now, it isn't urgent.
> sometimes there is double free crash: ink_freelist_free: trying to free item
> twice
