Ok, I will repeat that a real Core DUMP we have *never* seen during
run-time, even on heavier loads than this (much heavier).
Are you talking about "stack traces"? (i.e. couple of lines BUT IT KEEPS ON
RUNNING) these are normal.

|i have some code that will core dump jboss just about
|every time i run it within 5-15 minutes. i call it
|using 4 dos prompts running the same code. the code
|does a ejb create. each dos prompt i run uses 10
|threads, so, i guess im using 40 clients all doing ejb
|creates at the same time. each client does a delete
|all in the table, then does 10 inserts. i have my try
|catch block so that when i get duplicate inserts it
|will ignore the error, and just keep on going. i did
|this since this is the first ejb example i had in my
|book, this is all i have figured out how to do so far,
|and i wanted to test it out under load to see if what
|kind of performance i would get. i am quite
|underwhelmed and disappointed to say the least. maybe
|im doing something wrong in my code. yes, i realize
|most applications wont be doing this sort of load.
|anyways if you want the code let me know. like i said
|everytime i run it, i get a core dump in jboss.
