Research direction

No repository file, test, or entry point is named. Start by reviewing the PHP-FPM log entry alongside the Ubuntu, nginx, PHP-FPM, and reported 8.12.1-1build1 versions, then seek a reproducible failure. Done means identifying the cause of the worker SIGSEGV or documenting a reproducible case with enough environment details to investigate.

Description

I am getting the 502 error randomly. In the PHP logs each time it fails I see this:

WARNING: [pool www] child 2663814 exited on signal 11 (SIGSEGV - core dumped) after 1109.895754 seconds from start
NOTICE: [pool www] child 2690905 started

I am using 8.12.1-1build1
