Here's my code:

https://drive.google.com/file/d/0B3LYxKGJ4ZI_MV91SkxPVVlSOW8/view?usp=sharing

I don't have access to a debugger.

Run the code for a few minutes and it tends to crash with a core OutOfMemoryError.

Any suggestions welcome including regularly cleaning up memory used.

Thanks.

Memory allocated with the GC (e.g. using new) will never be freed if a reference is kept to it. Are you accidentally or deliberately keeping a complete history of all programs? Are you allocating any memory from anywhere other than the GC?

What OS? How much RAM? Are you compiling with -m32 (and conversely what happens if you compile with -m64)?
