[Bug]: Telemetry Reporter was terminated by signal 11: Segmentation fault: 11

[promisetochi]

What type of bug is this?

Crash

What subsystems and features are affected?

Background worker, Telemetry

What happened?

Adding the Timescaledb extension to a database results in a crash that terminates all postgres processes. This wouldn't necessarily be a serious issue but it makes it impossible to create db migrations using prisma because it always terminates the migration process.

Also, I'm unsure if this has anything to do with mac os sonoma.

TimescaleDB version affected

2.11.1

PostgreSQL version used

14.8

What operating system did you use?

Mac OS Sonoma 14.0 Beta

What installation method did you use?

Other

What platform did you run on?

Other

How can we reproduce the bug?

1. Set up a Mac OS environment with PostgreSQL 14.8 (Homebrew) and Timescaledb 2.11.1
2. Add Timescaledb to a database with `CREATE EXTENSION IF NOT EXISTS timescaledb;`
3. View postgres logs
4. Logs should contain a `background worker "Telemetry Reporter [1]" (PID 17408) was terminated by signal 11: Segmentation fault: 11` line

As a workaround, please try adding timescaledb.telemetry_level=off to your postgresql.conf, it should disable the telemetry altogether.

[promisetochi]

That worked @akuzm. Thank you!

I tried to reproduce this on my Mac, without any luck so far.

Hello @promisetochi,

I tried to reproduce the issue on my Mac, but I was not able to reproduce the behavior so far. Is the issue still reproducible on your system or was this crash maybe caused by an invalid response or an unreachable Telemetry server? Could you check if the error still occurs in your environment?

Hi all,

We have seen a similar issue on SUSE Linux with the same symptom. The workaround works, but we need the metrics service for our production environment.

Thanks.

Hi there, would you mind sharing a bit about your setup? How did you install TimescaleDB?

Need a bit more details in order to reproduce the issue.

Thanks!
