I should also say. We have tried the latest 1.6.0_18 JRE from sun and see the same crashes. Also we've tried switching to java-5 64bit and also see the crashes. This suggests it could be something in the low level native libs called by libjvm.so.

sudo update-alternatives --config java and select ia32 java
Will report if this is a good long term workaround - so far so good.
