It is a mapped folder, but why only on this particular command? All the data in this application is stored on that same mapped drive. Seems to me that if there were a disconnect, it would happen randomly with different tables.

Hmm, the error log is stored in a different folder than the actual data. But I see a couple of other more meta-tables in the same folder as the error log have been modified without issue.
