write.lock file might be present under solr/{environment}/data/index directory due to unclean shutdown. Removing write.lock file will fix the issue.

I was having this issue even when write.lock was not present. Here's what solved it for me:

1) Delete entire /solr directory

2) run ps -ef|grep solr to see any solr processes running

3) run kill -9 [solr pid] for each of the processes found in step 2

4) run rake sunspot:solr:start and then rake sunspot:solr:reindex

Hope this helps!
