Thanks for filing this bug in ubuntu. Could you please check in, or attach, /var/log/postgresql/ to see if there is a record of this crash?
I note also that there have been further updates to postgresql 10 in Ubuntu 18.04 since this bug report, have you upgraded, and did you see this crash again since then? ** Changed in: postgresql-10 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to postgresql-10 in Ubuntu. https://bugs.launchpad.net/bugs/1783568 Title: postgres crashed with signal 7 in __GI___select() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postgresql-10/+bug/1783568/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
