I’ve seen this twice, recently in https://github.com/bitcoin/bitcoin/actions/runs/21711098285/job/62615544269?pr=29278 and first in https://github.com/bitcoin/bitcoin/actions/runs/19305407337/job/55211418389. It seems unrelated to PR #29278. I am opening this as a separate tracker, as it’s worth investigating the root cause.

It seems unrelated to PR #29278.

Has it appeared somewhere else? If it was a problem on master, but it occurred twice in the same wallet-related PR, months apart, and nowhere else in all that time, that would seem quite a coincidence given how frequently the functional tests are being run.

Not to any of my other PRs/PRs that I reviewed.

I agree. It’s exactly the reason why I opened the issue here: I haven’t been able to reproduce it locally so far. I’ll investigate more soon.

FYI I locally did 160 runs of wallet_fundrawtransaction.py on the PR branch and got the error once (on Ubuntu, so it’s not windows-related). Didn’t get it in 120 runs on master. So it seems very rare indeed, but it might be possible to trigger the bug by running the test in a loop locally for an hour or so.

maflcko commented at 10:12 am on February 6, 2026: member

Note, it is possible to pass the same test name (wallet_fundrawtransaction wallet_fundrawtransaction ...) to the test runner. So if you have 64 cpu threads, you can pass it 128 times to the test runner with -j128. This way you don’t have to wait an hour and get the failure within the first try within two minutes.

(edit: Use at your own risk, check if your free memory is enough before running large -j )

160 is the new threshold.

Thanks for the help.

Closing as related to #29278.
