PHP 5.4 Branch is the one delivered with latest RED HAT ENTERPRISE / CENTOS 7 Release … don’t you think Piwik should be compatible with the latest Release of one of the widest spread enterprise Linux Builds?! :-/
well - using Piwik a few years now … and about half a year on this Server (Centos 7) - with this PHP Version (5.4) - and never saw zend_mm_heap Bug wihin Logs - and never had any Problems with the API. … Then I upgrade Piwik and got Problems with the API and start getting this Error … Doesn’t sound like a pure PHP Bug for me - does it sound like for you?
@matthieu,
upgraded Server as per your recommendations - Piwik 2.16.1 - Centos 7.2.1511 with PHP 5.6.22 - unfortunately I’m still getting zend_mm_heap corrupted sometimes.
