EVALUATION As was release-noted in 6u18, unless customers run with -XX:-ReduceInitialCardMarks when using 6u18, they are prone to run into all kinds of mysterious crashes. I'd suggest not entertaining any bug/service requests from customers who do not include -XX:-ReduceInitialCardMarks in their options list. This will keep sustaining from wasting their time re-analyzing crashes related to this.

Checked core file also confirmed this. As per communication from Asok, I closed this bug as dup.
