The issue was that we were calling erlang:hibernate before a receive .. after .. end call. Erlang hibernates the process before reaching the receive instruction and we therefore couldn't enter the after clause when hibernating. This is now fixed by using erlang:send_after instead and receiving that message instead of using an after clause.
