Yeah no problem Athos, I feel like maybe you can take it from here. The official fix is not mine and I haven't even tested that one so I don't think I'm needed here.

Yeah sure I can try if you're willing to help. I've tried to learn about how to work with .deb packages so I know the basics but I'll probably need some guidance. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2057576 Title: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php7.4/+bug/2057576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2057576] Re: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status
I think I've found what causes the SIGSEGV, see line 59 in
sapi/fpm/fpm/fpm_status.c: It uses scoreboard_p after it checks it for
NULL
57scoreboard_p = fpm_scoreboard_acquire(NULL, 1);
58if (!scoreboard_p) {
59zlog(ZLOG_NOTICE, "[pool %s] status: scoreboard already in
use.", scoreboard_p->pool); // scoreboard_p is NULL here
60return -1;
61}
Hope this helps.

I've tested on another 20.04.6 and I could reproduce it, here's what I did: place this php script somewhere accessible for web-server & php-fpm: http://localhost/status.php after a couple of seconds SIGSEGV warnings started to appear in the php- fpm log. ** Changed in: php7.4 (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2057576 Title: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php7.4/+bug/2057576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
