503 error while connecting to my ec2 elastic beanstalk deployment

i deployed my war onto elastic beanstalk and I am running many connections from an outside pc onto the service trying to load test.

I am getting this error

[ERROR] 2011-08-09 07:03:52,134 could not process CompanyBridgePromoResult

I am running c3p0 as my connection pool. I cannot see any errors on the server and its healthy.

Does amazon have a service to block out certain connections after too many connections from the same host? I tested locally I did not have any of these problems.
