Hello @acabarbaye,
All jobs on CircleCI have a max life of 5 hours, this is currently true of all executor types.
https://circleci.com/docs/2.0/configuration-reference/#jobs
Note: Jobs have a maximum runtime of 5 hours. If your jobs are timing out, consider running some of them in parallel.
The no_output_timeout option is useful for keeping the machine open in the event there are long periods with no output as to not assume the container has crashed. However, no job can run for 5 hours or longer.
is normal for it to take longer than 5 hours?
Almost certainly not but that would depend on what task you are attempting to perform. Most user’s jobs complete within minutes rather than hours.
If your job is suddenly taking unexpectedly more time than previously, we would recommend contacting support: https://support.circleci.com/hc/en-us/requests/new
