You're simply running out of heap space, so even a full GC can't free up
enough space to keep running.  The most likely cause is a memory leak
within your app(s), so a memory profiler would probably be the next
step.  It's also possible that you simply don't have enough PermGen
space available within the total heap to contain all the classes you
need, so you could try expanding that; if you really have a memory leak,
it will only postpone the inevitable.

There's some useful info here:
