What version of Solr? There's a known issue with distributed deadlock (since fixed) where under heavy load from multiple clients to multiple Solr nodes, you can get into a situation where it will stop accepting updates, but _will_ continue to serve queries.
If this describes your situation, dump the stack (jstack works) and look for the word "semaphore" in the stack traces. If Solr is waiting on that, that's your problem. SOLR-4816 (4.5) should alleviate this if you're indexing from SolrJ, and SOLR-5216 should fix it on the server.
