When JVM crashes (I've seen a lot of this) or corrupts object data
(and this too) this may be only JVM bug.

Try to change JVM vendor or play with various Sun JRE options (-client,
-Xint, etc). Our testing of JDK 1.3.1 demonstrated that Sun -server VM
was unusable at least on Linux and Windows platforms (unbounded memory
consumption, reproducable object data corruption, JVM crashes).
Switching to -client VM on all our servers cured the problems.
