+++ This bug was initially created as a clone of Bug #562055 +++ Description of problem: When running the test case here, https://fedoraproject.org/wiki/QA:Testcase_nfs_generic_secure After running the generic fs tests on the mount point for a while, the client behaved strangely, and commands like df, ps aux would hang, # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/vg_intels3e314401-lv_root 60084332 3182180 53850020 6% / tmpfs 4084324 0 4084324 0% /dev/shm /dev/sda1 198337 58851 129246 32% /boot <hung...> Seen the following from the server's /var/log/messages, Feb 5 00:00:52 amd-toonie2-01 kernel: RPC: AUTH_GSS upcall timed out.

Expected results: Tests can complete. --- Additional comment from email@example.com on 2010-02-05 01:51:08 EST --- Created an attachment (id=388995) sysrq-t output from the client when the test hang --- Additional comment from firstname.lastname@example.org on 2010-02-05 08:31:55 EST --- The same beaviour in my tests --- Additional comment from email@example.com on 2010-03-15 10:24:00 EDT --- This bug appears to have been reported against 'rawhide' during the Fedora 13 development cycle.

Comment 2 Jeff Layton 2010-05-17 11:33:19 UTC
Hmmm...looks more like some sort of generic networking problem -- i.e. problem creating or connecting the socket to the server: Feb 5 00:00:55 amd-toonie2-01 rpc.gssd: WARNING: can't create tcp rpc_clnt to server intel-s3e3144-01.rhts.eng.nay.redhat.com for user with uid 0: RPC: Remote system error - No route to host ...the kernel looks like it's doing the right thing here (hanging until the upcall starts responding).
Comment 4 Jeff Layton 2010-10-21 12:27:22 UTC
Is this still a problem in more recent RHEL6 builds?
Comment 5 Jeff Layton 2010-11-23 20:56:44 UTC
No response in quite some time and I've not heard of any problems along these lines since this bug was opened. I'm going to close with a resolution of CURRENTRELEASE under the assumption that this was fixed before release in some of the later kernels. Please reopen if that's not the case.
