As you have the GC-logs, you should be able to determine if it was a slow death (e.g. caches gradually being filled) or a sudden one (e.g. grouping or faceting on a large new non-DocValued field). Try plotting the GC logs with time on the x-axis and free memory after GC on the y-axis. It it happens to be a sudden death, the last lines in solr.log might hold a clue after all. - Toke Eskildsen, State and University Library, Denmark
