I had this same problem some time ago:


Turns out it's a problem with the kernel module using 32 bit ints for 
calculations that determine when to trim the cache.  I have patches 
against the 1.2.13 Linux module which ups the effective cache limit to 
about 80GB if you're interested.  I haven't adapted this patch to any 
1.3.x versions, but I suspect that wouldn't be too hard.
