PgBouncer server conn crashed Error with Jira DC on PostgreSQL HA
Hi Atlassian Community,
We’re running Jira Data Center with a PostgreSQL high-availability setup (Patroni + PgBouncer.HaProxy), and we’re encountering the following intermittent error in our logs:
May 05 04:12:09 jira-node-01 pgbouncer[56009]: C-0x55e185483240: jiraprod/jirauser@127.0.0.1:54248 pooler error: server conn crashed?
This seems to happen sporadically, and we can’t yet determine what’s causing the server connection to break.
What can typically cause PgBouncer to log server conn crashed? — is this a symptom of Postgres backend crash/restart, query issues, or something Jira could be doing?
Any insights would be greatly appreciated.
Thanks in advance!
