What I'm seeing is that if a query takes a very long time to run, and runs across the duration of multiple commits (I know, that itself sounds bad!), I can get into a situation where I have 2 searchers in use and 1 searcher warming, rather than 1 searcher in use and 1 searcher warming. Due to all the memory-intensive features I use, having 3 or more searchers open can cause an OutOfMemoryError. I'm not using master/slave for this application, so can't go that route. I'd like a way to see how many searchers are currently open that is external to Solr. This would allow me to block my commits until I see that there is only 1 searcher currently open. I could use JMX, but that feels like overkill - wondering if there is something simpler. -Michael
