If there is no change in query traffic when this happens, then it's due to what the index looks like. My guess is a large index merge happened, which means that when the searchers re-open on the new index, it requires more memory than normal (much less can be shared with the previous index). I'd try bumping the heap a little bit, and then optimizing once a day during off-peak hours. If you still get OOM errors, bump the heap a little more. -Yonik http://www.lucidimagination.com
