Still too many, IMHO. Can you please add a respective backtrace?

The manual[1] says:
| Whether PCRE's just-in-time *compilation* is going to be used.
(Emphasis mine.) See also
<http://www.pcre.org/original/doc/html/pcrejit.html>.
Which libpcre version do you use? echo PCRE_VERSION; should show
the relevant information.

Okay, it's been a bit more than 12 hours now since I did that and there has only been 2
Segmentation fault errors. Before it started spamming it roughly after 5 minutes of starting the
service. So it seems that did the trick.
What is that setting anyway? According to description it seems to be some just-in-time debugger. And
there are reports about this setting causing problems with regex. How's that?

Then simply add the following line and try again:
pcre.jit=0

Hi!
I'm missing pcre.jit setting in my php.ini file. I don't have any other php versions on
the server, because I scraped it all clean before installing php7 and the ini file got placed there
by php7 installation.

Have you contacted the developers of this forum software? Maybe
they already have a clue what might go wrong. If you should a file
a bug report with them, please add a link here for reference.
Also I suggest you check the pcre.jit ini setting, and disable it
if that's not already the case. Then check if the segfault still
happens.

Hi!
I'm running a big forum software, I have no idea what scripts there are that could be causing
this.
How can I help?
