I don't seem to be albe to find the root of my problem here. The server is
still not shutting down cleanly and I'm loosing all my data. i.e the server
is not surviving a restart:). Again this is only a problem with Tomcat and
jBoss running on linux with sun lastest stable JDK release. The same code
and setup works prefectly on windows 2000/NT.

Subject: RE: [jBoss-User] Core dump: ouch!
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.
