sqlite I/O error about vision HOT 6 CLOSED

You're probably right. The sqlite file access is probably not concurrency-friendly. There may be a solution, but in the long run we need to move lookup to a server. I'll investigate.

It looks like it might have to do with storing the file on an NFS mount.

From https://www.sqlite.org/faq.html:
"You should avoid putting SQLite database files on NFS if multiple processes might try to access the file at the same time."

Yeah the NFS mount sounds about right, I found that it doesn't only occur when I submit batches in parallel but also for just a single job. Presumably because others are simultaneously accessing mkgu.
