High Availability Starts with Removing Single Points of Failure NGINX is often placed at the most important point in a web architecture. It receives traffic before it reaches applications, APIs, services, containers, or backend systems. It can act as a reverse proxy, load balancer, SSL termination layer, caching layer, and traffic control point. Because it […]

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. That version is real. NGINX is genuinely well-documented, widely adopted, […]

22 Jun 2026 Automating DR site rebuild for a large Patroni PostgreSQL cluster

Problem: A customer running Patroni-managed PostgreSQL (PostgreSQL 15.17, Patroni v3.3) had production databases ranging from >2-3 TB up to a ~52 TB physical replica. Rebuilding the empty DR site from production relied on manual pg_basebackup executions and manual post-backup recovery steps, which was too slow, operationally intensive, and prone to human error for such large volumes. The […]

22 Jun 2026 PostgreSQL LWLock LockManager Contention caused by unpruned partition scans and high concurrency

Problem: An OLTP system using Patroni-managed PostgreSQL 15 experienced global slowdowns under load: CPU climbed to ~80%, large numbers of concurrent sessions, and application timeouts. The client reported bursts of traffic (hundreds of workers in parallel) routed through HAProxy to the leader, and provided PostgreSQL and Patroni logs, auto_explain output, and query samples. Key database […]

Problem: A production Patroni-managed PostgreSQL 15 cluster experienced periodic heavy queries that threatened availability. An example slow job ran for ~84 seconds and performed a full scan of a 1.8 TB partitioned table (arbor.CDR_DATA) that uses daily partitions starting in early April. Most clients connect through generic application users rather than distinct personal accounts. The […]

Problem: A 5-node Apache Cassandra 2.2.5 cluster (two data centers) reported severe per-node disk imbalance: each node was configured with five data_file_directories (e.g. /cassandra/data1/data … /cassandra/data5/data) but some mount points on individual nodes were near full (examples showed mounts at 93% and 95% used). On one node a particular keyspace (jessi) had large sstable directories […]

Problem: A production Patroni-managed PostgreSQL cluster (PostgreSQL v15.17, Patroni 3.3.2) experienced a primary process abort with SIGABRT during normal operation. Server logs reported that a server process was terminated by signal 6 (Aborted) and that the failed process was executing a COMMIT when the postmaster began terminating other server processes. Subsequent messages showed PostgreSQL could […]
