            Bug ID: 237458
           Summary: lib.libc.sys.sendfile_test on i386 on ^/stable/11 and
                    ^/stable/12 fails sometimes calling sysctlbyname with
                    ENOMEM
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: tests
          Assignee: testing at freebsd.org
          Reporter: ngie at FreeBSD.org

I'm not sure why, but i386 has an issue that occurs semi-regularly where it's
not able to run sysctlbyname cleanly, failing with ENOMEM. From
https://ci.freebsd.org/job/FreeBSD-stable-12-i386-test/lastCompletedBuild/testReport/lib.libc.sys/sendfile_test/hdtr_negative_bad_pointers_v4/:

/usr/src/lib/libc/tests/sys/sendfile_test.c:66: sysctlbyname(oidname,
&int_value, &oldlen, NULL, 0) != 0: sysctlbyname(net.inet.ip.portrange.first,
...) failed: Cannot allocate memory

This issue has been seen on ^/stable/11 and ^/stable/12 with i386, but not
^/head AFAICT.
