Subject: nfsv3 client process stuck in rwsem_down_failed_common()
Date: Mon, 14 May 2007 17:54:49 +0200 [thread overview]
Message-ID: <20070514155449.GA5169@janus> (raw)
On a 2.6.21.1 NFSv3 client box multiple processes got stuck with
this trace:
[<c02926e5>] rwsem_down_failed_common+0x85/0x180
[<c052a36d>] rwsem_down_read_failed+0x1d/0x30
[<c052a437>] call_rwsem_down_read_failed+0x7/0x10
[<c022622e>] nlmclnt_unlock+0x2e/0xc0
[<c02258da>] nlmclnt_proc+0x29a/0x2d0
[<c01f088e>] nfs3_proc_lock+0xe/0x10

[<c0125649>] do_group_exit+0x29/0x70
[<c012e73f>] get_signal_to_deliver+0x21f/0x2b0
[<c0103e96>] do_signal+0x56/0x160
[<c0103fde>] do_notify_resume+0x3e/0x40
[<c01041ae>] work_notifysig+0x13/0x25
Two processes had an independent shared read lock on different files
and when killing them with ^C they got stuck in state 'D' with above
stack trace. I'm not sure what brought then there other than that the
server went through a number of unusual reboots for testing purposes.
