<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>As of the recent <a href="https://github.com/sebastianbergmann/phpunit/releases/tag/11.5.29">release of PHPUnit 11.5.29</a>, <code>phpunit</code> jobs fail due to timeout.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>See <a href="https://git.drupalcode.org/groups/project/-/merge_requests/?sort=updated_desc&state=opened">Merge Requests</a> after its release, Aug 9, 2025, 3:13 AM EDT.</p>
<p>Observe most of the failures are due to hitting the 1 hour timeout.</p>
<p>Examples:</p>

<p>However, here is an outlier:</p>
<p>A job that passed <code>phpunit</code> after the release:</p>

<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>I've opened <a href="https://github.com/sebastianbergmann/phpunit/issues/6304">https://github.com/sebastianbergmann/phpunit/issues/6304</a>.</p>
<p>However, I am unable to reproduce this issue with vanilla PHP. This might be coming from up the chain in Drupal.</p>
<h3 id="summary-remaining-tasks">Remaining tasks</h3>

<li>Review and document the outlier, passing job.</li>
<li>TBD</li>
