CI "The job has exceeded the maximum execution time of N minutes"
By Daniel Zoghalchali·Latchkey
The runner stopped the job because it ran longer than the N-minute limit you set (or the default). The job did not crash - it was cut off at the bound, so the fix is a faster job or a longer, still-bounded timeout.
What this error means
A job is cancelled with The job has exceeded the maximum execution time of N minutes, where N is your timeout-minutes. It was still doing work at the limit. A transient slowdown sometimes tips an otherwise-in-budget job over; other times the limit is simply too low.
CI log
The job has exceeded the maximum execution time of 45 minutes.
##[error]The operation was canceled.
Common causes
A transient slowdown exceeded an otherwise-adequate limit
A slow dependency fetch or a congested runner pushed a job that normally fits within N minutes just over the line. A retry usually lands back in budget.
The configured limit is too tight for the work
If the job consistently needs more than N minutes, it hits the limit every run. Either raise timeout-minutes or cut the runtime down.
How to fix it
Right-size the timeout
Pick an N with headroom over the real p95 runtime, not the average.
.github/workflows/ci.yml
jobs:test:runs-on:ubuntu-latesttimeout-minutes:45 # headroom over the real worst-case
Reduce the runtime
Cache dependencies and build outputs to cut repeated work.
Shard tests/builds across parallel jobs.
Add per-step timeouts so one slow step fails fast rather than eating the whole budget.
How to prevent it
Set timeout-minutes based on p95 runtime with headroom.
Cache and parallelize to keep runtimes under the bound.
Alert on duration trending toward the limit so you adjust before it fails.

Can Latchkey fix this automatically?
Yes. Latchkey runs your GitHub Actions on managed runners that detect this failure, apply the fix, and retry the job automatically - self-healing is on by default.
