This is very probably an OpenVZ issue, it can be solved by bringing down the shared_buffers a lot. The restart works because the server is in fact down. I think pg_lsclusters showed online because of a stale runfile.
I was hoping that the memory allocation improvements in postgres 9.3 would solve these issues, but this post makes me think that they won't: http://www.postgresql.org/message-id/CAHyXU0xa5EgvjeH=4vp-ezdjds5kmquidivvtrljy-uz62y...@mail.gmail.com Does anyone know solutions?
