Based on the stack trace, this looks like the same issue as bug #77430.

Description:
------------
Roughly 5 seconds after fpm was reloaded, it segfaulted. Luckily this was a debug-build so I have a
stacktrace
03:43:38] NOTICE: Reloading in progress ...
03:43:38] ERROR: unable to read what child say: Bad file descriptor (9)
03:43:38] ERROR: unable to read what child say: Bad file descriptor (9)
** 03:43:43 php-fpm.service: Main process exited, code=dumped, status=11/SEGV **
03:43:44] NOTICE: fpm is running, pid 18379
