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.
