child pid 3264 exit signal Segmentation fault (11)

Hard to tell what might have caused that. The only segfaults I've experienced were caused by php itself, hence an update/downgrade usually helped.

Thanks for Your reply.
What should I update?
Nextcloud and PHP are (quite) current versions.
It's a shared host, so I cannot upgrade PHP.

Okay,

I have downgraded PHP to version 7.0.16 and the emails are shown again - everything is fine.
So, the problem lies in the combination of PHP_v7.1 and opcache.
Could be a server configuration thing.
Any suggestions what I could check?
I have the possibility to change/add entries in the httpd.conf and php.ini.

Thanks in advance.

I don't know for sure, but to me it looks like a php bug. Hopefully the next php update will work again.
