Job times out after 5 hours

I have seen this subject being discussed few times but could not see any resolution.
I received the following error: “Build timed out after 5h0m0s” in one of my jobs (Docker executor). Having seen this exact message in other tickets (How to increase job's runtime, Maximum build time for builds), I believe this is a hard limit set by CircleCI.
I have two questions then:

  • Is this limit documented anywhere?
  • Is it possible to increase this limit as I have an overnight long running job and it is normal for it to take longer than 5 hours?
    I also use the no_output_timeout option but this does not seem to be responsible for the timeout.

Many thanks,


Having the same issue using the macOS executor as well suddenly with no changes to build command
