Previous Comments: ------------------------------------------------------------------------ [2021-01-15 14:39:22] cmb@php.net Is this still an issue with PHP 8.0.1? ------------------------------------------------------------------------ [2020-08-06 13:06:33] buschmann at nidsa dot net When set opcache.jit=1205 the opcache_gui and prewarm and a quick test of the application seem OK now. (Only tested in httpd -X mode for now) It seems I cannot provide more info to come to the root cause. Thanks for investigating. ------------------------------------------------------------------------ [2020-08-06 10:16:20] cmb@php.net Thanks! This is apparently a tracing JIT issue.
