Nominatim: Resuming Indexing Processing Returned Error for Rank 22

Hi everyone,

I ran out of disk space on my Compute Engine VM instance whilst it was in the process of doing rank 30. So when I increased the disk space, and then promptly re-ran the indexing process from where it left off, I got a Keyboard Interrupt traceback midway through, on rank 22. Is it safe to ignore this?
