Depending on how big load you expect to take you can increase the memory 
for java.
Normally it has a 64 MB heap size, when that is used one gets a 
OutOfMemoryError
(garbage collector has to fail to free memory)..

"java -Xmx128m rabbit.proxy.Proxy " to give rabbit 128 MB heap...

If rabbit does have a memory leak (Im not aware of any, but that say 
very little)
this will help keep rabbit running longer, but not cure the problem.
If you have to big load for the normal 64 MB heap this will cure the 
problem...

How big is the cache when this happens? The cache index is stored in 
memory...
How long time has rabbit been running? (in days/hours/seconds/minutes)
How many requests have rabbit served since the start
How many request handlers do rabbit have at this time? Can you get a thread
dump? send a SIGQUIT to it (kill -QUIT <pid of rabbit process>) and you will
get a full stack trace for all threads in the jvm (hopefully this works 
after a
OOME).
The stack trace will come on the console you started rabbit in, so you 
may want to
redirect stdout to a file when you start rabbit.
