A business database server (proprietary DBMS engine, on Ubuntu 22.04) froze one afternoon during a backup that had been running for months without a single incident. Eight minutes of downtime, no data lost, but I eventually traced the freeze back to a memory saturation event the previous night, through a seemingly completely different mechanism.

A fleet of about ten VMs that deploy themselves via ansible-pull every 30 minutes. Every so often, one of them stops converging, stuck on a gpg: waiting for lock or SQL library used incorrectly error. The cause: a task importing a GPG key that nothing used anymore, somewhere in a shared role run by every VM.
