You've heard of the bisection method of debugging, right?
Eliminate half of your program and see what difference it makes.
Then eliminate the other half and see what difference it makes.
Instead of actually reading email, generate fake data and process it.
Instead of actually processing the data with an EJB, just throw the data
away.
See if either half causes your server memory to increase.
Repeat as necessary to narrow down the source of the problem.
