Do you have any custom configuration for mutex?
By default, mutex locks are files stored in storage/runtime/mutex. Can you start by clearing that directory and check if that fixes the issue? If it then happens again, have a look through the logs (starting with storage/logs/phperrors.log) and see if there’s anything there that looks like it could be related?
What happened?
Description
when an entry is edited and saved, the error occurs with message "Could not acquire a lock to save the element."
Steps to reproduce
Expected behavior
the edited entry should be saved successfully.
Actual behavior
the error shows, the stack trace is: { "trace": [ "#0 [internal function]: craft\controllers\ElementsController->actionApplyDraft()", "#1 /app/vendor/yiisoft/yii2/base/InlineAction.php(57): call_user_func_array(Array, Array)", "#2 /app/vendor/yiisoft/yii2/base/Controller.php(178): yii\base\InlineAction->runWithParams(Array)", "#3 /app/vendor/yiisoft/yii2/base/Module.php(552): yii\base\Controller->runAction('apply-draft', Array)", "#4 /app/vendor/craftcms/cms/src/web/Application.php(304): yii\base\Module->runAction('elements/apply-...', Array)", "#5 /app/vendor/craftcms/cms/src/web/Application.php(607): craft\web\Application->runAction('elements/apply-...', Array)", "#6 /app/vendor/craftcms/cms/src/web/Application.php(283): craft\web\Application->_processActionRequest(Object(craft\web\Request))", "#7 /app/vendor/yiisoft/yii2/base/Application.php(384): craft\web\Application->handleRequest(Object(craft\web\Request))", "#8 /app/web/index.php(12): yii\base\Application->run()", "#9 {main}" ], "memory": 29816648, "exception": "[object] (yii\web\ServerErrorHttpException(code: 0): Could not acquire a lock to save the element. at /app/vendor/craftcms/cms/src/controllers/ElementsController.php:1447)" }
