Odd memory error in PDP-11/04

Is there a hint as far as the affected hardware in that the ODT is
working, but the ram is not? The rom that is running ODT is also being
accessed for read correctly. Perhaps the problem is migrating since the
system halts however. A wild jump and a fault if the rom path is
affected might explain that.
I don't know if the rom path to the ODT code is different than the ram,
you guys would know better, but it is interesting that the console code
is being fetched, along with the data from the serial controller to
communicate with the console terminal, but the ram behaves so odd.
Insight as to how this is arranged would be good to have both for this
system and others.
