I am providing some follow up for awareness / completeness. According to my logs, the server was upgraded from Nginx 1.23.0 on 2022-07-18, and then upgraded to Nginx 1.23.1 on 2022-08-10: 2022-03-16T16:15:33+00:00 Nginx 1.21.6 compiled 2022-07-18T10:45:47+00:00 Nginx 1.23.0 compiled 2022-08-10T07:04:58+00:00 Nginx 1.23.1 compiled 2022-08-13T08:48:32+00:00 Nginx 1.23.1 compiled This issue first appeared on 2022-08-11 (a reboot resolved it), then 2022-08-12 at the same time of day, and again for 2022-08-13 & 2022-08-14. My provider graphs show the issue occurs at around 07:00 each day, which - perhaps coincidentally - is the same time that the Nginx 1.23.1 build completed. I am rolling back to Nginx 1.23.0 to see if that addresses or affects the issue, I will report back with findings after 07:00 tomorrow. Thank you for your continued attention and expertise, it is greatly appreciated.
