<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think it should be 2 instead of 3. Or do we need logging?</pre>

The first bit is for logging, the second bit is for auto-commit after each statement. 3 => 10 (binary).
Though, this patch doesn't seem to help. I still get the transaction deadlocked errors :/</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;"> With the ResourceMerger rewrite we no longer push one statement at a
time. We now push them in one large statement. This has been shown to
cause transaction deadlocks in virtuoso. It is recommended to set
log_enable( 3 ) in order to auto commit after each data manipulation
command.
Ideally we should have proper transaction support and each command in
the data management model should be a separate transaction. However,
this will have to do until we figure out how to do that.
