First, thanks for the quick response. Yes, it sounds like the same problem!!
I did a bunch of searching before repoting the issue, I didn't come across that JIRA or I wouldn't have reported it. My apologies for the duplication (although it is a new JIRA). Is there a good place to start searching in the future? I'm a fairly experiences Solr user, and I don't mind slogging through Java code. Meanwhile I'll follow the JIRA so I know when it gets fixed.
