Hi, I am having this error quite frequently while working with the proxies
for CompiledMethods. I don't understand....I am reaching a maximum in the
memory? I checked both, the amount of Objects I create and the amount of
memory and doesn't look that large.  I am in mac and I am even doing -memory
1500m and also setting HeapSize in plist.info.

Any hints?  I serached in Google and I found a bug with signed and unsiged
stuff...but i didn't understand and I am not sure which is the status today
(the threads were quite old).

Here is an example:


sweep failed to find exact end of memory

But this is just one example.

Thanks in advance for any help
