PCRE version too low for PHP 7.0
as you can read here: https://secure.php.net/manual/en/pcre.installation.php
with PHP 7.0.3 the minimum required version of PCRE is 8.38.
Your servers still use PCRE version 8.35. Dunno if I am the first who experiences this problem, but this leads to PHP sigfault crashes in my applications (TYPO3, Shopware) and they do not respond any more.
Any chance you're updating to PCRE 8.38 in the near future?
Thanky a lot,
