bummer, gc log rolled over... our Xmx:

root     12774  8.2  1.5 8833008 248832 pts/3  Sl   14:57  10:02
/usr/java/jdk1.6.0_12/bin/java -Xmx6000m -XX:+UseConcMarkSweepGC
-XX:+CMSIncrementalMode -XX:MaxDirectMemorySize=6G -verbose:gc
-XX:+PrintGCDetails -XX:+PrintGCDateStamps
-Xloggc:/usr/lib/hbase/bin/../logs/gc-hbase.log

I think we are hitting some sort of GC issue.
