Have anyone monitored the JVM with VisualVM? I have found that it looks 
like a specific memory pool may be filling up: Old Gen.  I'm trying now 
with:

-Djava.awt.headless=true -Dcom.sun.management.jmxremote -Xms10752m 
-Xmx10752m -XX:NewRatio=10

We'll see in a few days.  In the last few days, the problem have occured 
each morning at around 4:45.  I'm not sure if the same jobs run on the 
week-ends as well.
