Strange memcached behavior on stress test

I asked a question in my email about the stress test script, but I think
it might have gotten lost in the other information I posted. So I'll ask
Running the stress test with multiple clients eventually starts to
generate a lot of failures. After pushing a large number of GB through
the cache (like 64 GB+, don't remember the exact number) we started
getting a lot for failures on the test clients, like one was failing 30%
and another failing 60% of its sets. Restarting the server cleared the
problem until we pushed a lot of data through the cache again.
So what is going on? Is this the cache fragmentation problem? Is there a
fix for this problem? Other thoughts?
