Scheduled Posts Occasionally Miss Schedule with Real Cron Setup

[guruprasath1]

Hi WordPress Support,

We’re encountering an intermittent issue where scheduled posts are sometimes not being published as expected and instead show the “Missed schedule” status.

Our Setup:
We have disabled the default WP-Cron by setting DISABLE_WP_CRON to true in wp-config.php.

We’re using a real system cron job to run scheduled events every minute with this command:
wp cron event run --due-now

The Issue:
Most scheduled posts are published correctly.

Occasionally, a post misses its scheduled time and gets marked as “Missed schedule”.

Even after the next cron job run, the missed post does not publish automatically.

Running the above cron command manually also does not seem to publish the missed post.

There are no error logs or plugin conflicts that we can identify.

What We Expect:
Posts should be published at their scheduled time, or at the very least, during the next wp cron event run --due-now execution, even if they missed the exact time.
