From: John Baldwin To: bug-followup@FreeBSD.org, jpedras@webvolution.net Cc: Subject: Re: kern/116932: System locking up while carrying out remote ssh session on -current Date: Thu, 11 Oct 2007 16:42:19 -0400 Can you do 'show lockchain ' for the two threads blocked on locks next time and include that output. The two threads from the ps above are: 772 705 772 0 Ls *rtentry 0xffffff0003be5640 sshd 22 0 0 0 LL *rtentry 0xffffff000104e640 [swi5: +] 16 0 0 0 LL *inp 0xffffff00085726e0 [swi4: clock sio] 772 and 22 there might be a potential deadlock in fact. If you can reproduce with WITNESS and get 'show locks' that might help, too. Either that or get a core dump for use with gdb. -- John Baldwin
