Subject RE: Solr 4.3 Startup with Multiple Cores Hangs on "Registering Core"
Date Fri, 06 Sep 2013 14:25:40 GMT
Thanks for clearing that up Erick.  The updateLog XML element isn't present in any of the solrconfig.xml
files, so I don't believe this is enabled.  

I posted the directory listing of all of the core data directories in a prior post, but there
are no files/folders found that contain "tlog" in the name of them.

bq: I'm actually not using the transaction log (or the NRTCachingDirectoryFactory); it's currently
set up to use the MMapDirectoryFactory,

This isn't relevant to whether you're using the update log or not, this is just how the index
is handled. Look for something in your solrconfig.xml
      <str name="dir">${solr.ulog.dir:}</str>

The other thing to check is if you have files in a "tlog" directory that's a sibling to your
index directory as Hoss suggested.

You may well NOT have any transaction log, but it's something to check.
