I am running Postgres 9.4 server in a VPS running Ubuntu. It gets killed often (multiple times in a day).
This is the message from dmesg
Out of memory: Kill process 1020 (postgres) score 64 or sacrifice child
Killed process 1020 (postgres) total-vm:445764kB, anon-rss:140640kB, file-rss:136092kB
How to debug what is causing this crash? Is it long running queries or some misconfiguration of the server or lots of idle connections open?
