I recently added a second core to my solr setup, and I'm now running
into this "Lock obtain timed out" error when I try to update one core
after I've updated another core.
In my update process, I add/update 1000 documents at a time and commit
in between. Then at the end, I commit and optimize. The update of the
new core has about 150k documents. If I try to update the old core any
time after updating the new core (even a couple hours later), I get the
below error. I've tried switching to the simple lock, but that didn't
change anything. I've tried this on solr 1.4 and 1.4.1 both with the
spatial-solr-2.0-RC2 plugin loaded.
If I restart solr, I can then update the old core again.
Does anyone have any insight for me here?
