The second report here is confusing to me, I'm not sure how it could fail once but then succeed with no schema changes in between.

> Hi,
> I got this error on one machines after restarting (the node could have been killed due to an outofmemory error). It would crash on each restart on this error.
> I copied over the system table from another machine and deleted the locationinfo files and everything worked fine.
> I also had to delete 2 db files which coulnd't be loaded due to UTF-8 encoding errors. These rows were from the same table_feedfetch. The node might have memory errors, I'm going to check this. So it might be related to that.
