Info
It looks like we have some xml files without "NAGIOS_AUTH_HOSTNAME"

To find the corrupted files, you can grep

...

for "NAGIOS_AUTH_HOSTNAME", save the result to a list and compare this list with all xml files

look really different. So either the files are corrupt, or they are not in the right format:

Probably, the filesystem ran full during the conversion. The only solution is to delete these files and run the conversion again!
