Forum OpenACS Q&A: Java Out of memory errors.

Any java gurus out there know what the usual fix is when encountering an out-of memory error in java? I'm sending a large attachment (~2.5 Meg) using webmail and the queue processing routine bombs out with an out of memory error. I'm using the blackdown 1.1.7 version of java on a Redhat 6.0 machine. I can see that there are some command line arguments for setting the initial and max heap sizes, but I haven't had any luck with those.

Here's a traceback:
