2.7.0.a.20221206.0600: PHP ERROR File: /etc/inc/util.inc, Line: 220, Message: Uncaught TypeError: flock()

[woodsb02]

I've just updated from PfSense 2.6.0 to devel snapshot 2.7.0.a.20221206.0600.

I have email notifications enabled, and I am now getting an email every 30 seconds with the following message.

Notifications in this message: 1
================================

6:17:14 PHP ERROR: Type: 1, File: /etc/inc/util.inc, Line: 220, Message: Uncaught TypeError: flock(): supplied resource is not a valid stream resource in /etc/inc/util.inc:220
Stack trace:
#0 /etc/inc/util.inc(220): flock(Resource id #11, 3)
#1 /usr/local/www/xmlrpc.php(990): unlock(Resource id #11)
#2 {main}
  thrown

Most things seem to be working despite this error. Any tips on how to resolve it? I might disable email notifications in the mean time, which isn't ideal.

To try and assist debugging this, please see below extracts from the files in the stack trace (with a few lines of context preceding the trouble lines):

/etc/inc/util.inc (lines 217-220):

/* unlock configuration file */
function unlock($cfglckkey = 0) {
	if (!is_null($cfglckkey)) {
		@flock($cfglckkey, LOCK_UN);

/usr/local/www/xmlrpc.php (Lines 976-990):

$xmlrpclockkey = lock('xmlrpc', LOCK_EX);

XML_RPC2_Backend::setBackend('php');
$HTTP_RAW_POST_DATA = file_get_contents('php://input');

$options = array(
	'prefix' => 'pfsense.',
	'encoding' => 'utf-8',
	'autoDocument' => false,
);

$server = XML_RPC2_Server::create(new pfsense_xmlrpc_server(), $options);
$server->handleCall();

unlock($xmlrpclockkey);

I’ve worked out that this is being caused by the Pfsense community addon for Home Assistant here:
https://github.com/travisghansen/hass-pfsense

Once I disabled that integration in home assistant, the errors stopped in home assistant.

I’ll raise an issue over on their GitHub project.
