Ok, I managed to get this exception when CheckpointSynchMode is 1.
So when I do a query that only reads virtuoso when it does the
checkpoint is causes this
com.hp.hpl.jena.sparql.engine.http.QueryExceptionHTTP, why?

Hi,
**Why CheckpointSyncMode is 2 by default?
What happens if we set this value to 1?
I found "CheckpointSyncMode" section in this doc:
http://docs.openlinksw.com/virtuoso/dbadm/
but is it dangerous to set it to 1 and continue writing and reading
virtuoso while it does the checkpoint?
If dangerous, what can happen? if not, why it's not the default?
We have an API that calls virtuoso and it gets an Exception during the
checkpoint:
"com.hp.hpl.jena.sparql.engine.http.QueryExceptionHTTP: File not found"
