SolrException: Error opening new searcher

["Van Tassell, Kristian" <kr...@siemens.com>]

We're suddenly seeing an error when trying to do updates/commits.

This is on Solr 4.2 (Tomcat, solr war deployed to webapps, on Linux SuSE 11).

Based off of some initial searching on things related to this issue, I have set ulimit in Linux to 'unlimited' and verified that Tomcat has enough memory for the virtual memory needed to run the Solr index (which is 1.1GB in size).

Does anyone have any ideas?
