>Number: 4996 >Category: kern >Synopsis: NFS crash, possibly related to file bigger than 2^31 bytes >Confidential: no >Severity: critical >Priority: medium >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Mon Nov 10 07:20:01 PST 1997 >Last-Modified: >Originator: Alan Judge >Organization: Indigo, Dublin, Ireland. >Release: FreeBSD 2.2.5-RELEASE i386 >Environment: 2.2.5 box, with NetApp filer NFS V3/UDP mounted over 100BaseTX. >Description: Kernel crashed with supervisor page fault in kernel mode. Crashing process was nfsiod. Traceback: generic_bcopy nfs_writerpc nfs_doio nfssvc_iod nfssvc [BTW, is there any easy way to save what's printed and the traceback in DDB, to avoid having to write these things down before rebooting?] The really suspicious thing is that this happened while I was copying a large file to the filer. The resultant file was only 24K larger than 2^31, so I suspect that something blew up at 2^31 bytes. I don't have a core dump, but could probably repeat if needed. >How-To-Repeat: Copy a file larger than 2GB over NFS? >Fix: >Audit-Trail: >Unformatted:
