Thanks for all the suggestions! When I watch 'swap -s', it gets up to about 550M allocated, with around 7G available. The virtual memory allocated is only a little over 300M out of 3.8G.
When I look at prtcl, it shows 7.50GB allowed as zone.max-swap privileged. I still don't see any reason why it would be getting an ENOMEM. The program does start as root, then somewhere spawns another process owned by a 'broker' user and then switches itself to be run by 'nobody'. I'm currently looking through the source to see what system calls it uses, to see if there might be something there.
