Thanks Mike, Robert and Adrien, Unfortunately, I killed the processes, so its too late to get a stack trace. On thing that was suspicious was that top was reporting memory use as 20GB res even though I invoked the JVM with java -Xmx10g -Xms10g.
I'm going to double the memory, turn on GC logging, and remember to echo STDERR to a log and run it again on one of the indexes. I'll report back as soon as something interesting shows up. (Probably tomorrow sometime.)
