Though no evidence is left behind beccase the disk couldnt be used to indicate an issue. Your probably not around the console when this happens Bob? It may be possible to hook up a serial console and capture the panic if it is happening. There are other failue modes that leave no on disk trace as well, but well spit out a panic to a serial console. > On 03/07/2017 20:56, Bob Willcox wrote: > > Over the past month or so my network fileserver system (NFS support for my > > entire, small, network) has begun silently rebooting itself.
