25 May 2026 The Hidden Complexity of NGINX: When DIY Configuration Costs More Than Support

The Gap Between Getting NGINX Running and Getting It Right There is a version of NGINX that most teams encounter first: the one that installs cleanly, serves a default page, and seems straightforward enough that configuring it for production feels like a natural next step.

25 Sep 2026 Removing manual DR rebuilds after primary-site failover for a Patroni PostgreSQL deployment

Problem: A two-site PostgreSQL 13.4 deployment managed by Patroni experienced replication breakage at the DR site after any failover inside the primary site. The DR standby leader’s primary_conninfo was hardcoded to the former primary node’s address, so when the primary role moved to the other primary-site node the standby kept attempting to connect to the […]

23 Sep 2026 Resolving intermittent ORA-01013 in Debezium Oracle Source connectors caused by LogMiner timeouts

Problem: Debezium Oracle source connectors were intermittently failing with ORA-01013 (“user requested cancel of current operation”) every few hours. Restarting the connector temporarily restored replication. Connector configuration attempts included custom log mining parameters and raising database.query.timeout.ms from the default 600000 ms to 1200000 ms; the Debezium docs warn that setting database.query.timeout.ms to 0 disables the […]

16 Sep 2026 PostgreSQL replication slot repeatedly went inactive; replica walreceiver stopped and did not reconnect

Problem: A Patroni-managed PostgreSQL cluster showed recurring replication interruptions: the replica repeatedly reported a large streaming lag (initially ~565 MB, later observed ~5.5 GB) and the cluster’s physical replication slot on the leader appeared inactive (active = false, wal_status = reserved). Patroni logs on the primary had not recorded recent cluster events and appeared to […]
