Runner git upgrade to 2.40.0 causes job failure

Issue discovered in #30844 (comment 1328523350)

We are using docker executor

I'm referring to the gitlab-runner service logs with 15.9.1 it says something like

gitlab-runner[XXX]: Appending trace to coordinator...ok      code=202 job=REDACTED job-log=0-XXXX job-status=running runner=REDACTED sent-log=XXX-XXXX status=202 Accepted update-interval=1m0s

While on 15.10.0 reads like

gitlab-runner[XXX]: Appending trace to coordinator...ok      code=202 job=REDACTED job-log=0-XXXX job-status=running runner=REDACTED sent-log=XXX-XXXX status=202 Accepted update-interval=3s

On 15.10, after "appending trace", jobs immediately fail.
