In the process of troubleshooting #10490, we found that our wait received more than one sigterm.

However, when wf-controller sends sigterm for the second time (actually through argoexec kill), it may cause container-crash (signal processing is asynchronous), and we need this part of the log to support our troubleshooting.

Please do not open a pull request until you have checked ALL of these:

• Create the PR as draft .
• Run make pre-commit -B to fix codegen and lint problems.
• Sign-off your commits (otherwise the DCO check will fail).
• Use a conventional commit message (otherwise the commit message check will fail).
• "Fixes #" is in both the PR title (for release notes) and this description (to automatically link and close the issue).
• Add unit or e2e tests. Say how you tested your changes. If you changed the UI, attach screenshots.
• Github checks are green.
• Once required tests have passed, mark your PR "Ready for review".

If changes were requested, and you've made them, dismiss the review to get it reviewed again.

Use Debug level instead of Info level (already the amount of logs are expensive). Could the command contain sensitive text (ie result of secret/pw)?

Do we need this if #10523 works?
