RE: Memory leak??

[Fred Wan]

A memory leak even happens in the SimpleSwarmBug (java version), thus,
without a UI. The simulation runs 200000 cycles in 2m43s, in which the
memory usage increases from 19M to 29M. The files are enclosed. Any
suggestion is welcome. Is someone aware of a (freeware) program to track
memory leaks (which are mainly due to dangling pointers)?

Subject: Memory leak??


Hi,

Currently I (and others) are translating the code in the SimpleBug tutorial
from Objective C to Java. I have SimpleObserverBug running, but I discovered
a disturbing fact. I monitored the memory usage using top (UNIX), and saw
Kaffe (the process associated with the swarm code) grow from 13MB at the
start to about 29 MB after the bugs ate all the food (still increasing
thereafter). I checked jHeatbugs to see if the same thing occurred... and it
did, just not so fast. Does anyone know what may cause this and if this is
(as should not happen in Java) a real memory leak?

Thanks,
