Right after a routine OS security update and reboot this morning, our Neo4j graph database refused to start after working fine for months.
We were confused, until Annie, our AI SRE, surfaced an error analysis in Slack pointing to a port conflict between Neo4j and Datadog.
Both had been using the same port for months. Neo4j always booted up first, so everything just worked.
Except today, Datadog got there first and blocked it.
We gave DogStatsD a new port and told them to play nice.
