Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-apache (Nobody) <apache@FreeBSD.org> for maintainer-feedback: Bug 247487: www/apache24 segfault when reloading jailed https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=247487 --- Description --- Hello. After upgrade from php71 to php74 apache started to crashing with coredump when recieved -HUP (so after every logrotate). This happens only when running in jail, after upgrading on physical machine everything is fine. Same configuration with php71 is working fine. Bug is repeatable everytime I invoke `service apache24 reload` What can I do to trace source of problem?
