Subject Re: Solr nodes crashing (OOM) after 6.6 upgrade

It may happen that you may never find the queries/query time being logged
for the queries which caused OOM and your app never got chance to log how
much time it took...

So if you had proper exception handled in your client code, you may see
exception being logged but not see the query time for such queries.
