Have you configured your server to handle this sort of load?
While most deployments don't require handling 500 simultaneous
requests, it is certainly possible, but OFBiz doesn't come OOTB with
settings like that.
Take a look at the Technical Production Setup Guide on docs.ofbiz.org,
and make sure to configure at least the following (these are off the
top of my head, so there may be more):
1. Tomcat HTTP listener threads (at least 500)
2. app server (OFBiz) database connection pool size (at least 500 plus
a buffer, 20% over is usually good)
3. the number of database incoming connections available on your
database server (postgres or whatever) (a few higher than for #2)
If you're trying to run this with Derby you may want to consider not
doing that... I don't know if Derby in an embedded mode will do so
well with 500 simultaneous threads.

Hello,
Using JMeter I am trying 500 concurrent requests on /ecommerce module
First of all, I had to disable the recording of server hits -
because the crash came too early, but as soon as I tried again, I
got this:
