Makes me think that the problem is with a JSP page, which is being  
compiled in response to a request that comes in at around 10 am. The  
compiler is calling native code, which is crashing.

Does the site get updated overnight, which would cause the JSP pages  
to have new modification dates? Also, check the Apache httpd logs  
around that time and see if you notice a pattern of a certain request  
for a JSP that causes the crash.
