--- Comment #15 from Koichiro Iwao <meta@FreeBSD.org> ---
Hi, I'm also an AlmaLinux member and encountered the same issue with AlmaLi=
nux
9.5 and 10 Kitten. AlmaLinux 10 Kitten has glibc 2.39 but 9.x has older
versions.

In AlmaLinux 9, glibc-2.34-100.el9_4.4 for 9.4 doesn't have the issue but
glibc-2.34-125.el9_5.1 for 9.5 does. So I guess some changes between the
versions affects. It was the offending commit the reporter mentioned.=20

https://git.almalinux.org/rpms/glibc/commit/4da5357bcd7b44f2ee8891f477a5a6c=
34973ddba
https://gitlab.com/redhat/centos-stream/rpms/glibc/-/commit/6dbf26d6f46fce3=
7e63fcf2eec542b03ef4e0704

AlmaLinux team reverted the changes and it avoided the issue. I'm still not
sure if this issue is glibc bug or bhyve bug. At least I've never seen this
issue except bhyve. Have anyone seen this on bare Zen 3/4 machines?
