Public bug reported:

Steps to reproduce using stress test:
a) increment serial ID in all .class files of a largish web application (~100 KLOC)
b) rebuild web application archive (.war)
c) scp .war to loaded server (top utility load average >= 25) running tomcat (apache-tomcat-6.0.20) 
d) repeat from step A until JVM crashes (YES, I do see that crash happens in libc.so.6+0x8411b  memcpy+0x15b)
