Lukas, just to confirm your findings, I have the exact same problem and reported it about 2 months ago. Just like you, when all my stuff was running under 32-bit, it wasn't an issue because of the 2GB limit, but now that I'm using 64-bit for everything, it is a potential system crashing bug.

"certain" operations are done? (I am just looking for more clues)

upon my investigation, it seems that the io-cache translator ignores the cache size config option and on 64bit systems is can easily eat whole memory. On 32bit, it usually fails to mmap additional data due to 2GB limit to process
address space.
