CiviCRM causes session hang
At least for me, CiviCRM's session is locking for Wordpress's REST API and Loop back requests causing them to timeout. I first noticed this on the Wordpress Site Health check. Wodpress installs w/o CiviCRM or with CiviCRM disabled work fine.
The post there suggest passing the 'read_and_close' flag to session_start, but I have no idea what consequences that would have for CiviCRM.
Any thought appreciated.
