A few requests would work, and then all would fail with trying to allocate 7813304906544536728 bytes! Disabling opcache didn't help, reverting to 7.1.30 did (my ISP didn't offer 7.2.18 as an option to revert to). ------------------------------------------------------------------------ [2019-06-04 21:59:49] cmb@php.net Related To: Bug #78106 ------------------------------------------------------------------------ [2019-06-04 12:07:09] hardaqa at gmail dot com Description: ------------ Using Apache 2.4 via mod_proxy to connect to php.
