PHP 7.1 introduced Warning about invalid strings in arithmetic. And, yes, there is such "dirty" code in Drupal\Core\Menu\LocalTaskManager->getDefinitions() on line 187 ($definition['weight'] contains numeric string):
public function getDefinitions() {
$definitions = parent::getDefinitions();
$count = 0;
foreach ($definitions as &$definition) {
if (isset($definition['weight'])) {
// Add some micro weight.
$definition['weight'] += $count++ * 1.0E-6;
}
}
return $definitions;
}
This is throwing errors on every page load and flooding my database with them!
Also makes the error-log unreadable.
Caused by a typo in a custom_module.links.task.yml file
I put a ; after weight: 10
weight: 10;

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Thanks for the report and working to improve Drupal.
There has been no discussion of the problem here for 5 years. As #20 points out, we dropped support for PHP 7.1 some time ago. Therefor, I am closing this as outdated.
Thanks
