Ok, cool.
Do anyone of the proxies in front of rabbit handle the broken chunking 
from apache?
If not you should probably try the 2.0.36-pre3 release (will be full 
2.0.36 in short time
if nothing more shows up in my testing).

Could be the cache cleaner?
What value do you have for cleanloop?
How big cache do you have? (I guess 0, since you have other proxies).
Can you check the cache statistics and see if rabbit builds a cache?
(even if you set it to 0 it will use a small cache for image 
recompression).

Could also be GC. Can you try to to add " -verbose:gc " to your argument 
list
and see if it is GC-related?.

Ill look more at that later on.

It would also be interesting to know if java/5 is any better. I do not 
believe that
it will make any change, but if you have the option to try it (and I 
guess that you
can have a hard time trying it).
