well our observation leads us that this happens only during spell check. If we turn off the spell check we don't see this issue occurring at all from our 24hrs test run.
We have Jboss5.1 in production running Solr 4.2.1 (without spellcheck) no issues at all. Aditya -- View this message in context: http://lucene.472066.n3.nabble.com/Concurrent-Modification-Exception-tp4074371p4075752.html Sent from the Solr - User mailing list archive at Nabble.com.
