Mutex check failed

Note: The Mutex test in FireStats 1.5.4 or older is not reliable, try to run the system diagnostics test a few times and only follow the advice here it the mutex test fails consistently.

Some of the operations FireStats performs need to be synchronized to protect data integrity.

FireStats used the flock PHP function to perform this operation, but it does not work correctly on some servers.

If your Mutex test fails, you can either try to upgrade your PHP, or tell FireStats not to synchronize those operations.

This is generally not recommended, but may be the only option for some users.

To disable synchronization, you need to uncomment the line


in conf.php in the FireStats root directory.

Note: By default, FireStats comes with the file sample-conf.php, and you have to copy it to conf.php before uncommenting the line in conf.php.
