Job being killed on MacOS

General
1

Hi, how are you ?

I’m having a problem on a on-premise build using MacOS where a job receives a cancelation signal at random times (cloning, running a plugin or the commands of a step).

This occurs on a matrix build, where the first step finishes successfuly and the second one always receives the cancelation signal (other items of the matrix don’t even start and show a “Canceled” status).

Example logs from my pipeline:

... <Build commands outputting as normal>...
# Received cancellation signal, interrupting
🚨 Error: The command was interrupted by a signal: signal: terminated

Logs from the agent:

Finished job xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (Previous job of the matrix)
Assigned job yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy. Accepting... (step that receives the signal)
Starting job yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy
[Process] Process is running with PID: 63633
Canceling job yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy with a grace period of 10s
Process with PID: 63633 finished with Exit Status: 255, Signal: nil
Finished job yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy
Assigned job zzzzzzzz-zzzz-zzzz-zzzz-zzzzzzzzzzzz. Accepting... (another step in my pipeline)

System information:
Agent: buildkite-agent version 3.73.1+8506.d2135456fb5cedeb6c8c982fdb428de5d02c7cf9
System Version: macOS 13.6 (22G120)
Kernel Version: Darwin 22.6.0

Nothing seems to kill the related PID (dmesg wise at least). What could be causing this weird behavior?

Edit: Changed the post to General instead of Pipeline, sorry.

Hello @flavioarieta,

We’ll need to take a closer look at the pipeline where you see this happening. Could you please email links to a couple of builds illustrating the problematic behaviour support@buildkite.com?

Additionally, could you please share the agent configuration, any hooks or plugins you might be using, as well as, system logs around the time of the occurrence(s) of this issue?
