Hi folks,
I have problems with a NFS client. We run HelixServer
(realnetwork.com) on a FreeBSD 4.9-RC. For a while now
I see lots of nfs_getpages: error 70 and vm_fault: pager read error,
pid xxxx in /var/log/messages.
Turning Helix into debug mode says that it caught Signal 11 at the
same time the kernel is reporting the error.
In fstab my only options for nfs is ro,noatime,noexec. I search the
nfs/nfsproto.h for 70 (did I found the right code?)
nfsproto.h:#define NFSERR_STALE 70
Thats sounds like a timeout problem with the NFS server? Checked
for CRC error, none. Change the ethernet cable, still errors.
Is there some other option that I should use with mount_nfs?
The NFS server does not log any errors. I don't use rpc.statd.
(Search google.com, found nothing about error 70)
What should I try to debug the problem? Any other idea?
