https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=269297 --- Comment #2 from Rick Macklem <rmacklem@FreeBSD.org> --- Ok, sounds weird. I have no idea why ZFS would have anything to do with the KGSSAPI and upcalls to the gssd, which is the only case the timeout change affects. A few questions about your setup: - Are you running the gssd(8) daemon and using Kerberized NFS? - If not, there is no reason to run the gssd or even load the kgssapi.ko module. - Do you have "options KGSSAPI" in your kernel config? - What are you doing to "shutdown" the system? You can try changing the timeout from "5 * 60" to "60", since the timeout only needs to be increased slightly to fix the problem this commit addresses. The only case I know of that causes the approximately 27sec delay in an upcall is a misconfigured DNS. Make sure your /etc/resolv.conf refers to a valid DNS service or delete the file. -- You are receiving this mail because: You are the assignee for the bug.
