Hey all,
We're using a Solr 4 core to handle our article data. When someone in our CMS
publishes an article, we have a listener that indexes it straight to solr. We
use the previously instantiated HttpSolrServer, build the solr document, add it
with server.add(doc) .. then do a server.commit() right away. This works fine,
except that meanwhile, another process is importing new data from an SQL db
into the same core. For some reason, sometimes this process errors:

Not really relevant to this problem, because I basically want my real time
indexing to keep working in spite of this. However, when it's happening, I am
pretty sure this is causing my real-time indexing commit to throw this
exception:

Usually, I can get around this by basically creating a new HttpSolrServer and
trying again. But if the problem is very frequent, one more try doesn't work.
I don't like the idea of continually trying new solr connections until it
works. What's the proper way to fix this? I'm assuming adding a doc with a
commitWithMs of "0" is not any different than committing right away, but that
suggestion was raised as well.
