XF 1.5 Two PHP Warnings

[Sal Collaziano]

I've been seeing these in my error log since November 1st. Almost every day and about 10 or 20 each day:

[01-Nov-2017 08:13:29 UTC] PHP Warning: Error while sending STMT_CLOSE packet. PID=2812 in Unknown on line 0
[01-Nov-2017 08:13:29 UTC] PHP Warning: Unknown: Error occurred while closing statement in Unknown on line 0

Any idea what these represent?

These are generally happening outside of XF's control, probably from when PHP itself is being closed -- or maybe it's not XF at all.

But it looks like PHP is having problems communicating with your MySQL server at some point.

I don't think it's a big enough deal to have a lot of back and forth about it but I'll post what my server administrator said IN THE EVENT somebody wants to take a look into the possibility it's a XenForo thing.

The error you're getting appears to be caused by a mysqli call having an error when closing a MySQL statement.

I am not seeing any server-side errors or mis-configurations that would cause this issue and you will likely need to have a developer take a look to determine the cause of this warning. It is possible that these errors are simply a warning and that the call does go through after the server retries.
