PHP 8.3 and PHP-FPM Issues with Wordpress?

Anyone else experience issues running Wordpress on PHP 8.3 with PHP-FPM but no issues if PHP-FPM is disabled or no issued if using PHP 8.2?  I'm wondering the cause aside from in general being too new of a combination to be compatible with every plugin I may be using.  I use probably a lower than average number of plugins and never had any issues with them before trying the PHP 8.3 with PHP-FPM combo.

  Looks like I wrote too soon. Appears PHP-FPM may be the sole culprit as I'm seeing issues with it turned on now with PHP 8.2.

  Ehh. Problem was php max memory setting was set to the default 32MB which is too small for a many Wordpress sites and 8.1 that I was coming from been so long ago I forgot I had to up it to 100M (probably could get by with 64MB but my server has plenty of memory)

  It ended up being a two-pronged issue. The memory limit and the Cleantalk anti-spam plugin needs to use PHP Curl library which is not installed by default when you install PHP 8.x on Cpanel.  What made it hard was the Curl issue was intermittent but turning on Wordpress debug display I could then see the PHP Curl error.
