In a week i'm updating that server anyway so i have a maintenance window of around 30 minutes where i would be able to test things. ------------------------------------------------------------------------ [2019-05-22 21:34:41] dmitry@php.net unfortunately, no updates. I need a way to reproduce this crash. ------------------------------------------------------------------------ [2019-05-22 18:42:22] syslogbeta at gmail dot com Any updates on that? ------------------------------------------------------------------------ [2019-05-19 17:56:25] peku33 at gmail dot com Is there any update on this issue? I'm facing the same problems on debian buster, after upgrading from php7.2 to php7.3. I can observe this from ~january (after switching to 7.3.1) up to now with latest PHP 7.3.4-2.
